Action-Heroes in a Parallel Universe

What may have been in a parallel universe, had DC Comics published the Action-Heroes in the mid to late 1960s rather than Charlton.

When you get down to it, some stark realities reveal themselves through this exercise:

• All of these characters except one (Adam Strange) were principally defined by the teams they joined.
• Two had their own self-titled comics (Atom and Karate Kid...although Strange had a mini-series later).
• All were all zapped by energies (Thunderbolt/solar/Zeta/White Dwarf/chronological) which sent them to unexpected locales throughout the multiverse. 
• All of them were B-level characters that shined most when they were underestimated by those around them.

And all of them are near spitting images of their brethren over at Derby, if form if not always in substance.
