I'm looking at doing the exact same thing.
So trying to decide between a Stomp I/O or the duo with a blueboard.
I think it's possible with an extra app called Audiobus, it allows you to route audio from several apps to a single output on you iPhone/iPad
Only problem is switching patches on both apps guitar/vocal. I'm guessing 2 blueboards would be needed, one for guitar and one for vocalive, unless anyone can confirm 2 apps can be controlled with one board.
