OSX can do this already with aggregate sound devices. I'm frankly surprised not to see it in IOS. I just kind of figured it would be there if I ever wanted it.

Seems like a product with a market, but it takes guts to develop considering the precedent exists already in OSX and your business is just one little IOS feature-update away from getting hosed.

Edit: Yes the world is bigger than the fruit-themed-brand, but generally as goes IOS, so goes Android.
