Cafeenman,
one of Burt Rutan's later designs is laid-out along the lines you are considering. Wish I could tell you where to go to get the low-down, but don't have a thing on file. Remember reading an article on it , but it made my head hurt, so I didn't clip it.
Rutan has become a quasi-recluse so good luck getting specifics. If you do find the specs, I think you'll the prject interesting.
