I just installed a board in a newer RI w/ FX loop

lol you might aswell make a new thread on the subject, you'd get more interest that way.

The board should be very simple to install, as it's just the preamp configuration that's really different in a 2203, the MV pot will require a 1M audio taper which is what your normal channel has, and the amount of tubes is the same in the preamp so you won't have to drill/mod anything really. You could use the normal channel's inputs to host switches for value mods or something. Or even better, add an extra tube and you could have the Stock#39 Caswell mod in there.
