Please help identify LEGO Batman vehicle I'm trying to identify the set that this partial Batman vehicle belongs to. I believe the front center piece is part # 4623524 Roof tile 6x10, but all of the sets that contain that part don't seem to match the rest of the pieces. 



Here is the bottom front of the boat as it has an unusual shape that I can't find:
It appears to actually be an Iron Man set, with the dark green #4623524 piece swapped out for the same piece in black from a Batman set.

The base is 76006-1 Iron Man: Extremis Sea Port Battle



Based on the 1x2 slope piece with the Batman symbol, the #4623524 piece likely comes from 76000-1 Arctic Batman vs. Mr. Freeze: Aquaman on Ice
