In general I don't think you can use a BP/W for sidemount. The problem I think is that the wing will float up on you without the tank holding it in position. I could be wrong though, you should probably ask in the sidemount forum.
The issue with avoiding the inevitable 'taco' can be overcome with some inventive thread-work, or by using an adapter (such as the OMS Profile). Take a look at this thread: http://www.scubaboard.com/forums/si...ject-frankenstein-my-diy-sidemount-trial.html which details a conversion project I played with. It's better with a soft-plate though: see here for pics. Nonetheless, you can't beat a dedicated sidemount rig for function and light-weight IMHO.
