I've done this, successfully.
You need an accurate locking mechanism to get it into place in each screen, we use something that looks like a bathroom door bolt, only stronger, longer and with no slop in it. One of those on diagonally opposite corners. A metal plate on the floor for the locking pins to engage in. Done.
Use a commando socket for the power, and a EDAC for everything else.
Fine alignment is done as described, you have multitple sets of macros for each theater, multiple sets of measured colour data, lamp power trimming etc. One thing to be aware of it that Dolby servers only 'see' the macros associated to the first 14 buttons on Barco machines for some reason. I've not tried this with NEC's so I don't know what will happen there.
The caveat I always add to theatre owners/operators is that whilst the machine is mobile it is not a 5 minute job to move it, so don't be programming 11:00 in screen 1, 13:30 in screen 7. Usually they move it on Thursday night, with the programme.

You only need to have it mobile between 3 screens and you're up against this. Let's assume flat/scope + 3D flat/scope, that's 4 per screen.
Now on a Barco you've only got 12 buttons. With 12 macros this isn't an issue, but if you want to have scaler, satellite, BluRay etc that means more macros. So at first you think to yourself, no problem, I'll put the ones I'm never going to need as server cues, on the buttons. The theory is good expect you now find that the format macros you really want as server cues have vanished from the server. The workaround is the nice touch screen or cheap laptop, you can use that to call up the more obscure macros, putting your daily use ones on the first 14 presets.
If you try to make it mobile between more than 3 screens, at this time of the morning, I'm stumped!
