  It might work.

  You'd probably want two foils won the windward hull, then, positioned as close to the ends as is feasible, in order to counter the diagonal forces that would want to drive your leeward "bow" under when the ww hull is the lw hull.

  That's something I'd definitely try on an Elementarry first, just to see how well it works when you're not able to shift weight around in order to achieve a nice balance.

Mike, are you sure a foiling proa would need to shunt? Assuming the long hull (beam) carrying most of the weight with its "front" and "back" foils in a stable angle decalage with regard to pitch. The foil on the other side would determine heel and push up in "atlantic" mode and down in "pacific" mode. It works on the back of this envelope ;-)
