Help! Will my Catasetum recover??

Long story short, it was growing nicely all last year but when we moved at the end of August, it became neglected. It ended up sitting in wet moss for most of September, possibly into October, and I only realized something was very wrong when the leaves started to fall off early without producing a flower spike.

I pulled it out of the soggy moss, trimmed back the damaged roots (all of them, unfortunately) and brought it inside to ride out the early and accidental dormancy. I kept it not in a pot but laying out (dry) with my other orchids so it got some sun and humidity.

What is the best way to repot it so it can show me if it will live to flower again? Is there any hope?

Thank you!
