When I was in Victoria, Vancouver Island, I saw a VERY large kit busker called Dave Harris: look him up on Google for photos, I guess he had a panel truck parked nearbye! It must have taken him half an hour to set up! He had a footpedal bass and a custom made foot drum kit as well as several string instruments. His set up may give you some ideas.

Good luck, glad to see you are thinking of positive solutions to your problems.
