Personally I would like there to be an all around brawler-like class. One path could be a weapons using and the other teras kasi. This way you can be hand to hand or use techstaffs and vibroswords. Currently as a BH my favorite companion was Torian who was basically a techstaff using powertech. I thought it was really cool way to be melee and not be a jedi/sith. Something like that that can use armor and have weapons/tech and maybe can be a buffer/debuffer type who uses tech like "paladin auras". It's hard to think about because they kind of have everything rolled into all 8 paths...
