Given the potentially promiscuous showbiz lifestyle, I could see the original Trickster having a kid (and yeah, I know he had a son that was introduced in the Countdown To Final Crisis weekly series, but that book was so godawful hopefully the whole thing's been blown away between the New 52, Rebirth, and any other universe restarts that have occurred between Flashpoint and the Dawn of DC). Maybe give him a daughter who swipes some of his tools of the trade and becomes a new variation of Merry, Girl of 1000 Gimmicks. Maybe the daughter becomes a regular foe of the Axel Walker Trickster. Or maybe she has ties to Gimmix, who recently appeared alive in the new Blue Beetle mini.
