Would this work in a JAMMA switcher?

I have a robotron cabinet with one of those 19-in1 boards set to boot only to Robotron (cab has no buttons besides the start 1/2). Is there a reason why I would NOT be able to use a 2 slot JAMMA switcher and put the current board in one a lot and a Smash TV PCB in the other?

Yep, you should be able to. Not a problem so long as both boards are Jamma and the harnesses is Jamma. As far as I know 19 in 1s are always JAMMA .
 
The only curveball could be monitor sync but in theory both should be composite negative signal.
I've seen weirdness where a monitor likes one board and not the other so it may require some tweaking or it might just work.
