I'm happy to help out with a MotS run in the same capacity that I did on this one - i.e. assisting with trick-finding and planning and maybe running a level or two, but with someone else doing the majority of the work.
I asked Engy about MotS after we finished DF2, and he wasn't up for it - I think one big project was enough for him for now, especially since his main reason for starting on this was just to improve his old 2004 run.
There was a guy called roy_hess working on a MotS run over on SDA who gave up because not enough people seemed to be interested in the run. The thread is here:

If you wanted to, you could always try getting in touch with him to encourage him to carry on with that run, or to start again (I briefly started looking for tricks and found a nice timesaver on level 2 which is mentioned at the end of the thread I linked to; I'm sure there's plenty more to be found). Alternatively, if someone from this place has the time to take on a MotS run, I'll be happy to help them out with it, too.
Leaping straight across from cliff to cliff and skipping most of the level was actually one of the things I looked into back when I was playing around in MotS. A corpse boost
almost certainly wouldn't be possible because you don't have a straight path (or anything near to one) from the starting cliff to the exit, and your corpse doesn't actually bounce off walls - it slides if it hits them at an angle, but if it hits them straight on it just comes to a stop. The alternative is to force jump off a stack of sequencers, reach the other cliff and survive, then run to the exit. At the time I attempted this and concluded it wasn't possible. I've gotten better at explosive jumping since then so if someone starts a run I'll give it another look, but I'm not too hopeful.
Edit: By the way, I'm pleased to see that people enjoyed the audio commentary. I was worried I was stumbling about and 'um'ing and 'er'ing a bit much.
