hey sorry to hear about that man.. can you get a first class medical? if you can then i see no problem in you flying for the regionals. you will more than likely have to get a soda attached to your medical, but that should be no problem if you can do everything just fine.
and on the thrust reversers, they do have to be at idle, and there are release buttons on the thrustreverser themselves, but they are located where you grab them from so if you can move them, you can probably push in the releases to pull them back. i think some people were confused about that on here. on the crj 200 there ARE thrust lever release buttons built into the thrustreverser handles.
