There were a few times I didn't count if someone said, "I like all these ideas...", but my head started going squishy after a while so I might've missing some.

Anyhow, one way or another, it looks like most folks have Invaders, Guardians, and Doc Strange as their favored JB comics.

Somebody upthread mentioned a SEVEN SOLDIERS type of thing, but more in line with how JB would do it, from a GENERATIONS angle, using all these ideas. I kind of think that'd be interesting.

And if I had to choose between the top three, I'd go INVADERS only because of the chance to see Union Jack, Blazing Skull, Whizzer, Human Robot, the Destroyer, Gorillaman and so on. I'm all for the Golden Age approach.

Your interest in Black Panther is surprising and what a welcome surprise that would be.  I think that the character would play to all of your strengths, but I have a hard time imagining a good BP time travel story arc (it would have to come at some point).

Obviosuly, you've never read of T'Challa's epic encounter with King Solomon's Frogs.

Dr. Strange!

And, even if JB already worked on this character... the Silver Surfer.
