I think it's the opposite. Xstream is the easiest to mod. The reg body is cylindrical almost completely when you cut the mouthpiece away. Then you drill a new hole up. The old hole is blocked by an adapter. The adapter is also quite a simple model.

I am not thinking about the shape of the house but the internals with the smal holes, I belive it is very important in wich directions those are compared to the mouthpiece hole. As I wrote I am looking forward to see how it will work out, so keep up the project. If it donīt work out, all you have to do is to buy a new house.
