We've been thru the real main seal business any number of times before, it's not the most pleasant of jobs but straightforward enough.

As to the Ultramatic, just my own opinion but I can see replacing a transmission with something non-authentic, most especially just for a few leaks. The Ultramatic gave good service behind the straight 8s, it really wasn't until the V8 era that they became a bit problematic. That aside, a lot depends on where the leaks are. If it's the front seal of course the transmission has to be removed but leaks at the selector shaft, throttle pressure shaft, and rear seal are all very easily dealt with with the transmission in the car. And if I had to remove the transmission to do the front seal, I'd think hard about taking the opportunity to replace some bushings and friction parts.
