This means I'll have to make new traits to replace feats, I can take a look at other games to get some inspiration for this. I want to retain a good bit of what some of the feats in d20 does, and class abilities. But I can also grab things from AoW, and take a look at ikrpg, warmachine, 5e etc. This is actually going to be a lot of work, simply because of mass, and is the largest advantage to staying with d20.
