I love reading your threads, gives me a bit of motivation to get things done on mine too
With the trans bolts, I seem to recall that a bunch of them have open tops on the castings on the transmission where they thread into, or at least the casting it threads into sticks out free of the main body of the transmission. Worst worst case scenario, if the stripped bolts are on any of these spots, maybe you could just chuck a longer bolt through and a nut on top to secure it? If that makes sense. Like this picture, you can see the tops of the pan bolts showing from above, when looking down. If you just got a bolt a bit longer, you could probably thread a nut onto it easily enough with some fancy finger work, and get yourself out of trouble. Obviously just be careful not to over tighten and crack the casing, maybe chuck some rubber washers under them.
Just an idea, I'm all for ghetto fixes if they work!
