In theory, this should work, but you cannot connect both streams to the same 
output ports unless you ensure that only one will play at a time. Otherwise, 
the outputs of both streams will intertwine or otherwise confuse the output 
layer. Whenever you want to attach two streams to the same output, you have 
to put a post plugin in between that implements your 
switching/mixing/whatever policy. In your case, you could create a crossfade 
post plugin (which is yet to be written) that allows you to trigger the 
crossfade from your frontend.
