Honestly, I'm not sure what is impeding 'clear channel' bridging through Asterisk at this point. if there is an appropriate format available in both channel drivers, nothing in Asterisk is going to manipulate the payload of the frames as they pass through unless it is specifically requested.

With the addition of framehooks (used by the T.38 gateway), it would be completely possible now to implement this multiplexing/demultiplexing as a 'shim' that sat on top of a channel.

Thanks for your feedback. Anyone else that has opinions in this? It's important that we all are on the same path moving forward. 

The clear channel discussion I was thinking of was the ISDN data discussion a long time ago. Bringing an unspecified channel from ISDN into an app that converted it to something else and sent it back.
