What about the option of setting up the cab as jamma on one powerr switch and mame on another switch. That way you could easily switch jammas when you want to play them and then power them down and boot up mame. All the button, TB, and joysticks should be able to piggyback jamma/mame connection. This is only my theory, not to be taken as truth!!!

I see what you saying (I think, lol).... so I'd basically install two power supplies with maybe with a 3 position switch and two full jamma harnesses.... then wire everything up duplicate... then maybe use the 3 way switch for no power in the middle to anything... and maybe power up for Jamma and down for PC ???
It should work... but seems like a lot of work (I'm a lazy gamer over here, ;) )... I wonder though if there'd be any risk of power feedback coming from the "ON" power supply following the connections from the PS to the monitor down to the "Off" PS and into any boards attached??? :-\

Also you would be getting feedback through the monitor connection . It would be safer to use a dual jamma adapter(with some modified wiring).

My cab is set to either Jamma boards or mame PC.
Basically I cut all the wires from the CP and then joined them back together with molex connectors. I then wired an Ipac4 (4 player cab) to the inverse molex connectors.
i have a Jpac too.
To swap from Jamma to mame i undo the molex connectors and plug them into the ipac molex leads. The unplug the jamma harness from the PCB and plug it into the Jpac .
BE CAREFUL WHAT YOU DO WITH THE 12V OUTPUT FROM THE JAMMA P/S AS IF YOU PASS 12V THROUGH YOUR IPAC/JPAC IT GETS FRIED!!!!
THIS COULD BE AN ISSUE IF YOUR COIN DOOR NEEDS 12v.
I use mame 99.99% of the time so i just unplugged the 110v output from the arcade distribution box to the arcade P/S so the arcade P/S is "dead" and no 12v issues, nor 110v live plugs sitting next to a PC that I am forever fiddling with.
If this does not make sense tell me and i will think before i type

So you fully swap everything then...
I gave the swappable controls some thought too... but it seemed like a big hassel for setup. How long would you say it takes you to swap everything?

ya know i did this for a buddy a while ago he wanted a mame machine that could play mame games + at the time it wasnt on mame golden tee 99. anyways i did run into a little bit of a problem as i built the cab myself so i didnt have anything existing to start with. this posed as a problem as sometimes the button wouldnt work right on mame...for some reason. after golden tee came out on mame i updated it and removed the old board...but then again i wired up the controls to the ipac and to a jamma harness. just some info on this for ya.

the time it takes to pull out 2 molex connectors and plug em into another connector, plug in the 110V PS and pull the jamma harness out of the Jpac and into the PCB....... Got to be 45 seconds max.
I then have a 4 player jamma cab/ or 4 player mame machine
