I've certainly not seen that figure used before - as to if it'll fit, I don't know. The feet look like they might be a problem, but then again, they might not be, and it is a cool figure. The boxed set it comes in is pretty expensive, but comes with two other red dragons, so is probably reasonably priced based on that, and the others do look like they'd definitely fit.
@
McHotcakes , may I ask if this thread is also good to be used for looking for suggestions for what figures to use for a mod? There's probably a few guys down the line where that help would be useful for me. There's one in particular I'm thinking of (though I'm not planning on doing him just yet).
