If you use doubles with a traditional BCD you will DIE!!!!
Just kidding ... using your Balance to dive doubles is well within the realms of possibility and there is nothing wrong with doing so. It certainly won't kill you as long as you take precautions (such as keeping in mind your lift requirements).
The thing is ... for deco diving it isn't really adequate at all. You don't just need the capability to dive double cylinders, you need lots of other things as well, and your Balance simply won't supply those things.
If you get the chance though try to dive doubles with your Balance. It should give you some experience about what it is like diving with them underwater and, if you do get a BP/W, it might be easier to adjust. Or it might not ... just musing out aloud here.
The point is, its always fun to experiment with new toys. So try it out, just don't expect to be able to use it for deco diving.
