Please don't remove the widget suffix. The suffix was chosen to work with
alsa-lib's control parsing code. The term "Playback Route" is appropriate
because it is playback only, and it is a routing switch, not a source or
sink.
Also, what's wrong with just having a single "stereo" widget instead of
two "mono" widgets? I added stereo (2-channel) support to DAPM quite
some time ago. You just have to have two routes in and out.
