That seems possible, except then the number of input and output channels
will take their default values of 2.  If the developer wants to choose
different channel values but still have the UA choose the buffer size what
would we specify for the buffer size, maybe 0?

I think it's best that if the UA chooses the buffer size, then the value
should still be a power of 2 and be the same every time the event handler
is called.  It's easier for developers that way.
