It is much easier to go the other way! Groove Tubes do a plug in SS rectifier for as a replacement. I tried it once, but went back to the tube one.
If you have an amp with ss rectification, you will need to make sure that the tube rectifier can produce enough power (unless you are really looking for sag). With tube rectification the amp will not sound as tight. That's what happens on my amp with swtchable rectifiers - not a mesa but a McIntyre from 1993 - a Bluesmaster, 2xEL34, about 6 12AX7's! - It has 6 active tone bands, pentode/triode, half power, switchable rectifiers, mid-cut on a footswitch, 2 channels (crunch and lead) and a master volume bypass - too many controls really!
