You could just tape over the hoods and build them up bigger, like we used to do with our boyfriend's class ring.

I have carpal tunnel syndrome and I usually have to make things like paintbrush handles bigger with duct tape so I can go for the long haul. It bothers me some on the bike, but I take B6 and it helps. If I were doing longer distances, I'd build up the hoods with bar tape to make them cushier and bigger.
