I'm satisfied with two of each.

There were various Sweeps depending on which scene of the movie you want to reference - excluding Scourge we see 2 in the reformatting scene, 4 as they transform out of their reformatting, 3 entering Galvatron's ship, 4 on the horizon of Autobot City, 2 in the attack runs on Autobot City, 3 in the death of Ultra Magnus - so I've gone with 2 as per the reformatting. My TR & Legends & Generations ones can fit in the remaining gaps

I've already got 3 TR Sharkticons and 1 Legends, so figured I'd keep myself limited to only 2 SS Gnaws, which would match the 2 ER Allicons I ended up getting.
