Ok, now that you weeded out some stuff and have a new band plan, take a step back and look it over very carefully like someone else just proposed this to you. Ask yourself what will these new channels do that cannot be done with existing GMRS or MURS? Be honest.
If you are still convinced its the thing to do then get ready to be whipped and beaten by amateur radio operators, CBers, the FCC and anyone else who has an interest in radio. It will make the worst beating you've had in your life look like a day at the spa. After all the smoke, broken bones and scars heal you still have the FCC to convince and they aren't giving away any frequencies in recent times. They want to auction everything off and squeeze every penny out of every frequency they can.
Good luck with your plan and I actually hope you get somewhere with it just to prove some of us wrong.
