I’m all for playing around, but the OP’s reasoning does seem like a lot of work for little reward. It gives zero privacy and if someone wants to interfere they can still just key up on the input while your talking and wreak havoc.

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.
LTR trunked repeater on GMRS?

That's not the point at all.
What I'm doing is to experience and learn how to operate and maintain a trunking system. I've never used one or owned one, so this is a small project for me. It may not be a full multi-channel system, but I'm using the resources I have and can get atm. I currently hold a GMRS license, and LTR is the only legal option. It will remain a private repeater for just me and my family; it won't always be on unless needed. But this is just an experiment, so I can play around with trunking.

LTR even on a single channel provides some pretty nice little functions. For one, talkgroups and all call groups come into play. Yes you could do it with a community repeater controller or a repeater that supports multiple tones but on the subscriber end you would be forced to scan in a not always convient way. You also gain the whole access control capability with not a single consumer grade GMRS radio being able to use the repeater. User ID information is standardized across vendors. Seriously, does anyone else have a mix of Motorola radios that do MDC1200 and Kenwood radios that do FleetSync with the only common ground for ID being a digital protocol or is it just me who runs into this issue which is why I abandoned analog for personal radios? Motorola and Kenwood (and I assume Icom) made multiple radios that could support LTR and were type accepted for Part 95.
It's not a bad starting point IMO.

LTR on a single analog channel sounds like a complete disaster unless it's just 1 talkgroup without multiple users and is strictly used for access control. There is no way to monitor the channel like CTCSS/DCS, which I believe is a requirement for GMRS. LTR is useless for a single channel IMHO.
Using a LTR controller on a single repeater on GMRS is a great way to eliminate the idiots who do idiot things on repeaters. Listening to them scratch their heads trying to figure out why they cant scan for the PL on their chinese garbage radios to access the repeater is fantastic.

We had several Trident LTR Controllers in the early 90's I just looked and several are on ebay $40 to $100 range
I think the shop just tossed two or three of them that were in the back room collecting dust. Being a part timer now, I don’t get first dibs on dumpster interception anymore.
I still know where two more are racked with some GM300’s as RX,TX that I moved to the side to make room for the NXDN trunking racks that took their spot.
I may make an inquiry to see if they want me to dispose of them so they don’t have to and play around again with this. I have a few CDM’s that were on that system back in the 2000’s , and still have the programming to match the controller settings 😈
Does anyone know where to even get programming software for those Trident LTR controllers?

If I remember it was DOS Based on 3 1/2 floppies
Maybe someone over on repeater builder has it posted or still has it still.
What should I use to program it, since I don't have floppies or a floppy drive? I just bought a raider trident LTR controller

If you can get a LTR controller, get it programmed and interfaced to a repeater, go for it.
You will learn. It will increase your skills and knowledge. Have fun with it.
It will keep the CCR's out.
99% of the programming wa done with a terminal emulation software. We used procom orginally but now I use Putty or SecureCRT. Still have 3 tridents in use for conventional stuff. If local you need a NULL modem on your serial port. Ints menu driven and the manual has the steps.
