I have read various stories about a confrontation between Boba fett and IG88.

I think there was an idea that IG88 was trying to intercept and destroy Boba fett in Slave 1 in bespin orbit but he was blown to pieces by missiles from Slave 1. IG88 was attempting to destroy Boba and claim the bounty on the millenium falcon.

I doubt they filmed anything like this but if they did. absolutely want to see it.

There is a lot more empire strikes back alternate footage left to be released. It would be nice to see a workprint version even if low quality just to see all the stuff that got cut.
