Here's a thought; because PTWs are so back-breaking expensive, you could always incorporate GBB platforms into the mix. Still not cheap, but much cheaper compared to PTWs. A little more realistic and cool/fun to use.
Thinking further though, a separate channel may be a good idea. It's a tough cookie..
