Put both servos on a Y connector and plug into the FMA just like you
would plug into the receiver in a normal installation !

Yes, it would basically do what you want.

However, if it put an aileron down, it would lift that side of the
plane, true, but would also pitch the nose up, which would then cause
it to move the elevator to poke the nose back down.  I imagine it
would work, but not that well -- if the plane twisted to the left, it
would lurch back to the right, and as that happened the nose would go
up or down and then correct ... under certain conditions I imagine it
could cause oscillations where it never recovers and keeps making
adjustments to both the aileron and elevator.  (But of course, that's
a concern with any sort of auto-pilot system.)

A better idea would be to do as the other poster suggested, and put
both ailerons on one channel with a Y cable.  You might need to adjust
the connector on one servo or use a servo reverser if both ailerons go
in the same direction when you do that.

If you do need to use flaperons (or spoilers, or air brakes) with this
setup, get a mixer to put in your plane, and then you can plug the
Co-Pilot into the aileron side, and your flap channel into the other
side (and your radio won't be doing the mixing for you anymore.)

Mike,

I use the exact same set up, a BTE Fly'n King with a FMA co-pilot. I,
too, wanted it for a camera platform. The Co-Pilot is a VERY good
system, but hook it up to a Y on one channel. I built the Fly'n King
with flaps and they provide plenty of slow flight performance. I don't
see a need for flaparons. I have had excellent results with an
on-board video camera and transmitter, the co-pilot makes the job of
flying a steady course for the camera a cinch. The device is worth
every penny. Mine is set up with remote switching so that I can fully
control the model for loops, etc. with the device off, and switch it
on for level flight.

The Fly'n King, a camera, and the Co-Pilot are a perfect match.
