I created a pirate theme for ENworld. I believe its in the store area. Simularly, I created a mercenary theme for Soldiers of Fortune.
Hmmm ... Eliminating races, classes, paragon paths, epic destinies, feats, multiclassing/hybrid classes, etc ... and universally replacing them all with themes.
Themes seem far more robust than most races. Dragonborn, Tieflings, Deva, etc could all work as themes.
