If you are going to move the hinge line forward for the flaps you may as well move the entire hinge line forward & widen the ailerons as well.
You are going to reduce your aileron area anyway when you make half the length flap & wider ailerons at smaller angles will be more effective
than thin ailerons at large angles. Then top hinge/bottom drive them.

Or, easier still, fit a second aileron servo & drive the strip ailerons individually. Then use the smarts in the transmitter to drive them both down
as flaps when landing. Or drive them both up & use them to kill lift. Some elevator mixing will probably be needed as well.
