I would recommend asking on j-pouch.org, there are a lot of members there who have their pouches either removed or disconnected (or both).
I don't have personal experience with it, but from what I've read, the people who do poorly with a disconnected pouch are people who either have chronic pouchitis/cuffitis that doesn't resolve with diversion, or people who have loop ileostomies that are very difficult to manage. It sounds like your pouch issues don't have to do with pouchitis or cuffitis, which bodes well for leaving it in, especially since you've already been diverted for so long.
Healthy bowel always produces mucus, releasing on a daily basis is normal.
