Alrighty, took a little longer than I'd planned but here's some modifications to the R2 stats that might work for you. Let me know what you think and if it works for you.
Looking at it myself, the only real sticking point that bothers me is the Flying Locomotion. Beyond that, possibly remove the Fire Extinguisher, too. I think a good switch-out for the first might be a Secondary Battery or possibly even upping the internal storage for 5kg. Honestly, I'm not sure what else I'd do with it, as the rest of the stats strike me as fitting the standard R2 unit fairly well. Stats/skills/feats strike me as good, and its just those equipment things that get to me more than anything.
