Unless the repeaters are far enough away that they can't receive eachother if the inputs/outputs are opposite and you don't use different tones on each channel they will lock up in a loop.
Otherwise it depends on how you configure them, how far away from the repeaters the users are and how far away from eachother the users are and what function you are trying to accomplish.

What exactly are you trying to do here?

Actually it's possible. We did this about 15 years ago to create an "ad hoc" repeater where no local machine had coverage to support comms for a bike race. Both radios were "opposite" of each other and created an in-band repeater. It worked.

Then the radios must have been set up for one-way repeat.

Icom: - 2730 cross band repeat in one direction only??
Ias it possible to program my Icom 2730 to only repeat in one direction?
Cross Band Mesh (Or Mess) ???
Cross Band Mesh (Or Mess) ??? Been wondering if it's possible to setup multiple operators in a community with cross-band repeaters to operate in a shared mesh configuration. I've made some drawings, but it looks like quite a mess. Anybody ever discuss this? "Doubling" looks like the big hurdle.
Are you thinking about connecting two repeater stations together that operate in the same operating band? When you state loops and same frequency sets it sounds like you are trying to set up something that operates in the same operating band. That type of operation is not cross-banding.
Cross banding means connecting two separate stations that operate simultaneously on different operating bands. I.E. A station operating in band "A" receives traffic and keys a station operating in Band "B" and transmit the same traffic, and vice versa, to allow the users operating on two different bands the ability to have interoperability with each other.
If two stations operating in the same band on two different frequency sets, by means of some type of an audio tie connection, would be "Multicasting". If multiple transmitters in different locations are operating and transmitting on the same frequency set and are keyed at the same time that would be "Simulcasting".

If crossband repeater one is programmed:
146.100 PL100.0<->446.100 PL100.0
And cross band repeater two is programmed:
146.700 PL100.0<->446.100 PL100.0 and
ALL users are on VHF, with their radios programmed:
RX: 146.700 PL100.0
TX: 147.100 PL100.0
It will function as an in band repeater IF there is adequate isolation/separation between the radios on VHF to prevent desense.
The down side is that if the UHF frequency is found, a malicious user could cause problems easily. I would probably use DCS rather than PL, as most hammy toys don't act on or use PL reverse burst. The triple squelch crash would fast become annoying as ****.

If each radio was programmed:
VHF: 146.550 UHF: 446.100 with out CTCSS/DCS or the CTCSS/DCS was the same, then it would lock up the second you keyed up on either frequency, until the time out time expired.
If you set up a cross band repeater to link to inband repeaters(one on VHF and the other on UHF), AND both repeaters had repeater 'tails' long enough that the cross band repeater could hear, then you would get a continous cycle, bouncing between the repeaters, that would render the repeaters useless.
