I'm still bummed there weren't more WW offerings in JLU. Not an Amazon or Circe or Steve Trevor or nuthin'...
Steve Trevor's omission is very easy to correct.
If you want the Classic Lyle Waggoner version, all you need is a General Eiling figure and a Blackhawk head casting. Paint the casting's hair & hat to match the look & uniform... and BINGO!
If you want the show accurate Steve... all you need is a Clock King body and a head cast from a character you think has the same jawline. Aquaman and/or Future Superman (from Batman Beyond) would easily do the trick.
But to be honest, when it comes to civilians and love interests... it would have been terribly unfair to skip someone like Clark Kent or Lois Lane in favor of Steve Trevor. Steve might be important... but as far as kids go... he's not that big of a draw.
