a slanting view of mine, with asymmetric twin-fuselage derivative:
On the twin with the V-tails, why not join the two "inner" tails in a larger inverted-V-tail and do away with the outer tails? Note that this would leave all sorts of room for a central pod/nacelle, of whatever kind, between the two fuselages. The ultimate evolution might be a push/pull twin-engine pod (piston or turboprop), or a twin jet pod (
ala' Ar-234C) with no engines on the fuselages.
