So long as the wing tips still stall last, you're all good. As for CG issues . . . that's where the bigger tail comes in.
This "coupling" is nothing new. The Navy has been doing this on their planes to help aircraft fly slower for carrier operations and they love it.

Wolfgang,
 
'Tain't that simple..........
 
It could be done only as the flap is put into reflex as one does not want the ailerons extended below the wingtip as the flaps go down as this can make it easier to stall the wing tip.  Reflex ailerons would be possible by a mechanism to lessen the length of the linkage between sticks.  This assumes that when one is in a fully reflexed banked turn there still is enough travel in the upgoing aileron (reduction of lift) and, even though the down going one may not go below the wing tip, lift will occur because it is going out of reflex.  Now, one need only consider the effect of this on stall propagation and CG issues.

The ideal would be to have some coupling between the ailerons and flaps.

Pursuant to my last post, if you have a look at my YouTube video entitled "San Diego Lancair," as the plane accelerates away from the helicopter shooting the footage, you can see how far up the flaps are reflexed.  The ailerons are also reflexed to line up with the outboard end of the flaps.  This has proven to be the best configuration for my particular aircraft.
