I'm sure everyone here is familiar with the combination of the
horizontal stabilizer and elevator to make a stabilator. I think I have
even heard of the concept being used for a ruder. My question is has
anyone ever made a plane taking the concept all the way and made a
"wingeron"? My guess is no one has, seems to me it would be difficult
to do and maintain the required strength with out adding a lot of weight.

It's probably not practical for a real plane but I thought it might be
an interesting experiment to try on an RC plane.

The A-7 had variable incidence wings though not for roll control. I believe
this was to change the angle of the fuselage for carrier landings.

Many missiles have full flying "wings". With no takeoff or landing
requirements these lifting surfaces are tiny. While very maneuverable, they
have such small wings that many airplanes can turn inside an attacking
missiles and thus escape it's lock.
