Probably the easiest approach is to use a RigBlaster-like interface between
the rig and the DXDoubler.

At the station I sometimes operate from that uses a DXDoubler, it
sits to the left of the keyboard, on the desk. This seems to be a
good location, as my logging program (TR) can send a DVK message
with an ENTER key press. My right hand homes on the keyboard,
and the left hand homes more often on the DXDoubler.
With a remote switch, you could put it anywhere, of course.
I think the biggest challenge might be to make sure the cable to
the extended switch doesn't pick up RF - maybe put some toroids
at either end.
