A long stroke v-twin would be difficult, given the current architecture. There is precious little room under the frame, above the valve covers, for this shorter stroke version. A taller frame, to accomodate the engine, would cut even further into the fuel tank area. A boxer engine would be easier to work with for several reasons...although a severely canted four or six inline, like the new BMWs, might work.
50 mpg ain't gonna happen with anything the size of a barn door, with the aerodynamics of a parachute. A more aerodynamic vehicle would kill the look...especially with the suspension covered. I don't think we want clones of cages. Some things may be desireable, buit they aren't always practical...or pretty. Nice to dream about, though. Perhaps a hybrid is the answer.
How about something along the lines of the Honda Magna engine? A V-4 would give more head room and the Spyder seems wide enough to accomodate more width. That might allow a significant bump in CC's. And the Magna is no slouch in HP either.
