Was hoping somebody would take the Flash and do something with them, or maybe make the Speed Force a team of people with different speed based abilities rather than the power within all of them. The Martian Manhunter just being a bounty hunter type of space alien from Mars could also be really dope. 

*taps deeper into DC lore and randomness*

- Starman and/or Stargirl could have altered powers and be powered by the 'Starheart' or simply call the energy 'Starfire'

- Toyman could be a smaller action figure style hero instead of Doll Man (could even be a robot)

- The Cheetah could be the fastest hero in this universe

- 'Green Arrow' could be the name of an experimental plane, or plane suit (think of the blue guy from Centurions)

- Aquaman could just be some type of aquatic version of Ultraman (red and silver Japanese hero) or something like the Creature from the Black Lagoon

- Dr. Midnight could just be a late night superhero doctor/surgeon without the blindness or blackout bombs

....that's all I've got for random altered concepts off the top of my head. Everybody stay warm! Preparing for this snowstorm!!!
