Thunderball could be placed in a Spider-Man set, since there's precedent of him being a solo operator against the Web-Head.
The Wrecker could exist by himself in a classic Thor set with other 60s-era Thor characters like Absorbing Man, Enchantress/Executioner, King Cobra, Radioactive Man, etc.
Then Bulldozer and Piledriver could either be in a Masters of Evil vs Avengers set (think the "Under Siege" era) or maybe split across a series of Secret Wars sets?
Of course, Thor vs Wrecking Crew is a much more efficient way to get the team, but this way seems more fun and gets us even more potential for new/improved characters!
