There seems to be a bit of a gap between jewelled legs and black legs. And as there are many more armors than legs some DEF 14 legs might be a good idea to bridge that gap. Players might not feel "stuck" with lower level legs and look forward to getting a new pair sooner. I have created some sprites for two pair of legs: dwarvish, which are DEF 14, min. level 65; and stone, which are DEF 14, Fire 102%, Ice 102%, min. level 70, and a patch to add them to the game.
