What's Spider-Man 2099 doing there?

Before his untimely demise, this version of Miguel was a member of this AU/Earth's iteration of the Avengers (Earth-98120):

Being awesome because he’s being written by PAD LOL

When Thunderbolts debuted, it was villains masquerading as heroes and over time, they actually became heroes. Somewhere back in a thread I made a post saying I would like to take T-bolts back to something similar...rather than villains masquerading as heroes, I would have villains who might actually want to convert over. Having these three lead that team would be an ideal dream for me. Barring that...they absolutely deserve to be in the Avengers. I've wanted Melissa in the Avengers since Forever came out. If done correctly...it could almost harken back to Cap's kooky quartet.
