1.) I could dig it, but with vampire Batman there's three heroes already in Gotham. 
2.) A Stargirl super-soldier could be fun.
3.) I vaguely remember the Everyman Project, wasn't familiar with Amazing Woman but I remember Fury. Countdown was wild.
4.) I wish somebody would take the idea of riding a giant thunderbird for one of the Hawks. Rescuers Down Under changed my life lol
5.) The OG Ben10 of superheroes has always been a tough sell. IDK how you'd change it up for this altered universe other than just becoming one hero?
6.) I've always wanted to genderswap a character like Black Canary (Blackbird), Tomorrow Woman (Tomorrow Man), or Wonder Girl (Wonder Boy) for something. 

The main thing is just taking the concept and making it your own. New look, powers, person under the mask, etc. The names are just about the only thing that remains from previous iterations. Superman hasn't been Clark Kent since the 60's and he was an adult when he landed in the 1930's. He's basically a lazy Kryptonian living in the arctic who only saves the world when he's [i]super[/i] bored. Batman isn't Bruce, and he's a mf vampire (did I mention the Trinity was loosely based on Gods & Monsters?). And WW's Amazons are more like an off-shoot of the New Gods here with Motherbox/teleporting tech. 

And so far we've got my Deadman powered by the green Lantern. An occult styled Flash called Speed Demon. A Martian potentially posing as Plastic Man. And a female spin on Bane called Bone Breaker. 

This group of protagonists might actually be more out of left field than the Tangent universe.
