The WL conversation tends to be about three brands of WL that roughly conform to martial, half martial and full support. I'd probably build a subclass each on the Fighter, Paladin, and Cleric platforms, although elements of the current build on the rogue chassis would work in the middle there too. Generally, that would equal 1/3 WL, 1/2 WL and full WL if we wanted to steal some terminology from spell casting, If you built the 1/3 WL first, you could just add to it for the 1/2 WL and add some more to the full WL. Tie the three together with some overlapping abilities, whether identical or just similar and just add some juice at each step. That's the broad strokes of a very fresh idea anyway.
