Personally I would like to see a Wolverine/Jubilee teamup movie in the vein of the mid 1990s comics, a hugely underrated run of low-key stories which were a fantastic character showcase for both Logan and Jubes.
Wolverine is at his best when he has someone at his side with whom he can exchange some quality dialogue and snarky comments, and the dynamic between him and Jubilee has always been fantastic.
That is, until Marvel turned her into a vampire in the middle of the Big Two going completely insane over the past few years. Comics got weird, and not in a good way. That's why I've been checking out more indie books of late.
Anyway. That aside, a Wolverine movie featuring a proper Jubilee (not the glimpsed Jubilee from X-Men 2 and 3) and featuring a straightforward story, basically a superhero buddy movie, would inject some humour and energy into a subset of comic films which are thus far somewhat bleak.
