Access through the rear galley?

I'm considering providing a way through the galley. I bought an SUV tent that snaps on the rear and would like to allow a connection between the two. Since my TD is 4'6" wide, I am considering making 24" of the counter a flip-up, like at the pub. The cooler could go underneath (removable) and there could be a fold up shelf (with a Rubbermaid box) above.
I would put a small door in the bulkhead. We don't need the extra space now, but with a growing family, it could be nice.
Any thoughts?
