If you're in a pinch and want the beast on the board, and it's on roughly the right size base, I wouldn't have a problem with it. It looks like a plastic Star Wars model; I don't know if you'd want to tear it up and put Dwarves on it, or just use it as is. It wasn't a foolish idea for a proxy. I like what Andy Manic_Miner is doing with his better, but not everyone is a conversion nut. I say use it and be happy.
