Any thoughts to fix and/or round out the last 20 points?

not in modern age

One obvious one is:

Invisible Woman 110
Mr. Fantastic 100
The Thing 100
Bombastic Bag-Man 90

Total: 400



However, if you don't have the Bag-Man, then you could add a Special Object for around 4 or 5 points, depending on which one you want to add. The Scorpio Key would give the team PC, which would be good. The Crimson Gem would make Spidey into another mini-Thing. The Blue Lantern helps Invisible Woman's use of both TK and Barrier and doesn't require a "pick up" roll.

Nice. Real nice.

I was going to say much the same thing. I recently played a 500 point FF team:

Invisible Woman 110
SI Johnny Storm 100
SI Benjamin J. Grimm 100
Mr. Fantastic 100
Bombastic Bag-Man 90

This team played great together, the synergy was amazing. I used Sue as strictly a support piece with the TK and PC, and kept her top dial. Johnny with his Running Shot/Pulse Wave combo was awesome, aided of course by Reed and his +2 Perplex. Ben was the big surprise. I'd never played the LE before, always the starter version. After playing the LE, I am not sure I'll ever play anything but. He was awesome for me. The Indomitable makes all the difference in the world.

Anyway TS, if you are playing Modern Age, I am not sure what else you could add to that team? A Special Object would only add 5 points, and you'd still be 15 points short.
