How about an engine with the crankshaft running out the front and back,

you could mount a prop on the either end? That way you could have
counter-rotating props using the same engine.

Two props mounted on a common crank would turn in the same direction,
so they wouldn't be contra-rotating (I assume that is what you meant)
but might be counter-rotating if they turn in the opposite direction of
the other engine's props.

What I meant was putting a clockwise spinning prop on one wing, and turning
the other engine around, so it would be a counter-clockwise spinning prop on
the other wing.
