I'm very curious. I had read that Secret Six would be returning later on, which would be the best thing ever for DC to do. But if that doesn't happen (or well, if it does, then just apply this question to that haha), I was wondering what random characters

I did have a story like that, a few random characters sent on a mission off-world. Let's see, just off the top of my head:

Rocket

Hawkwoman

Plastic Man

Black Alice

Rainmaker

Ryan Choi

Does that work?
