Not entirely, Zerg. It's a possible future, though it's based on so many elements from the DCAU that it's incompatible with the mainstream DCU, even before the reboot. Main trouble points are Warhawk's parentage, and the number of Robins that became Batmen before Terry - Terry's strength was that he was the second Batman, not the umpteenth.

So it's essentially a separate universe, set in the near future (something that is usually called a "Possible future"), that combines DCAU and DCU elements.

As for Arisia... she's a pixie cheerleader from a family of GLs. She started at the local Graxos III equivalent of 16-ish. She's been around since the 80s, and hasn't aged much, if at all.
