That would be hard to do. But I guess anything is possible. Maybe you can do what this guy did:
He basically took off the eye ribbon connector off his board, and soldered on a DM eye connector on his board to accept DM style wired eyes. Wired eyes are even less than what you are willing to spend for eyes... and more durable than ribbon material.
Plus, you don't have to mill the body to fit wired eyes on a 06 minion/PM6.
