How to make a modern Mighty (Patreon)

So, the face of a 2.5 inch Mighty figure is the same size as 4 inch MODERN Sonic's (hilarious quirk of classic figure proportions and Jakk's choice of scaling.) Plus I'm told the neck peg of a 4 inch Sonic is compatible with this head, so you can make a modern Mighty figure simply by painting his eyes blue and sticking his head on a lightly modified modern Sonic body.
