Other than buying an EX, you'd be looking at reaching out to someone like Spazzy to see of he could make one for you. Not going to lie, though...a custom will likely cost you as much as the EX...
I PM'd Spazzy on Statue forums about this. And yes it would cost anywhere from $300-$500 for the custom piece. Because of its clear resin nature. Let alone the connector that connects it to the statue.
