There is at least one. I think it uses sodium dithionite, but I'm not sure. Haist writes about it in his book.

2) I'm leaning towards a permanganate / bisulfate bleach vs. dichromate. I hear this really softens the emulsion but that colder temperatures can help. Can I slowly cool the film after being washed from the 1st developer before I put it in the bleach? The bleach would be cooled as well. I'm thinking about 55-60F. I would increase the bleach time by about 2x.

Alessandro Serrao, who also posts here, uses a process that runs at a consistent 20C (or maybe lower) to avoid stressing the gelatin as much as possible. He is able to get good results. I didn't pursue the permanganate bleach much as I found the dichromate easier to use, despite the toxicity (it is reusable, unlike permanganate bleach).

3) I'm planning to use HC-110 according to Jordan Wosnick's formula because I like HC-110 and have it handy. Is there a big reason not to do this?

The HC-110 trick works well, but do a test roll first to see how it goes in your set-up. And let me know how it turns out!
I have to confess that it's been a while -- about a year -- since I've done any reversal processing. The last procedure I tried (which worked quite well) involved a strong solvent-free Rodinal first developer, followed by a separate reduction step with a thiosulfate bath. I describe it (with a link to the original) in a post here:

Hope this helps
