I would actually advice doing color reversal first, as it's quite a bit easier compared to B&W reversal, considering there's no re-exposing needed in color development. Temperature is always the key, though. And loading correctly can be quite tricky.. Good luck!
That is probably a good idea, but I'd still need a physical mechanism / contraption to develop the film. An altered Jobo reel might be preferable from my point of view.
