There are a few 4 seaters and 2+2s on permit, though they don't appear for sale very often.
The DR1051 with the 105hp Potez may fit the bill, but be careful about gross weight with 460m, its close to the limit.
The D140 mousquetaire is the best load lifter with 180hp lycoming and approved as a 5 seater. It will lift its own empty weight as payload, but it commands a high price.
You can get plans for the 1050, D140 or DR250, but you need a lot of time and patience, though you would be eligible for a permit to fly.
