If you brace the motor mount over to the spar

I think there's a problem here. If the Cozy is
anything like my Velocity, the wing spars bolt
to the aft face of the center section spar. The
suggested setup would have the braces penetrating
the wing roots and spars to reach the attach points
on the center section spar. I suspect Nat would
have something to say about this...

The loads are minimal. Bolt them to the wing roots.
And bolt them to the motor mount on the back end
near the rubber joint. When you take the wings
off unbolt the brace tubes first. Don't drill
holes in the spar web or wing roots. Bond on a 
couple of composite  brackets to bolt to instead.
A four inch by four inch bonding area will be more
than enough. Actually one brace tube would be enough
the second one is redundant.
