The two channnel conversion will be superfluous. The single channel
will do all the job fine (like in 756PRO, Orion and others).

My DSP transceiver uses such technique and it works fine. 
You can see more info at (http://users.ints.net/skidan/T03DSP/),
I will update it soon with the schematics and other info.

All the best !
