I have one crazy idea for you :) you can try to setup alsa jACK plugin and then setup jACK to use your alsa bluetooth device. Thus if jACK supports mixing itself (which most probably the truth) the whole setup should work as you want. Unfortunately, I don't have jACK installed so cannot give it a try.
