It looks like the mess you'd get if you crossed a Piper twin with a Cessna twin with some idiot adding "an extra leading edge" between the engines - and to stop them falling off.
I'm going to go back to original guess and say it's an Experimental prototype Piper.
Those are 360 Lyco's under those cowlings or I'll eat my hat.
