But it would be less expensive and possibly attract more people (of a certain type at least) if you just painted it OD and used canvas bucket seats, the only food service collecting the "outgoing", and called it a C-47 (or R4D if you prefer).
In US last operators I saw were Provincetown Boston (out of business about 15 years ago) and Shawnee Airways in Orlando (not MCO, Herndon). There also used to be a Ford Trimotor operation from Sandusky Ohio.
Bet the insuranace, permits and associated mickey mouse will make it cost prohibative.
