He already gets a reward... the reward is not needing to spend the skill points on those gadgets and dedicating his points solely to Force, which is quite dangerous if evoked properly. He'd probably start with a heap of shielding too after awhile. He shouldn't get some bonus for sticking solely to the right side of the skill screen, unless sticking entirely to the left side of the skill screen got you something too.
What you said isn't really an argument against my point. Adaptation is everything, even Obi-Wan pulled a blaster when the situation called for it. So what, should he have lost some mystical Jedi power for using an OMG GUNNER WEAPON? No, I don't think so either.
