Spoilerons might be a better way to slow for a landing because by bringing both ailerons up you are lowering the AOA on the whole wing. This would allow you to fly nose high and thereby increasing your induced drag. A harrier approach if you will.
Not quite a harrier approach, but they are extremely useful to land my Falcon 1.20 and Bobcat .50's.
They permit me to keep the nose high exactly as you mentioned, slowing the plane, and preventing it from overshooting.
Without the flaperons the planes decend with too much airspeed and you cannot hold the nose high.
The flaperons also prevent tip stalling tendancies.
