I would say no -- this is similar to adding positive incidence to the wing -- it will compromise the entire flight envelope. Your plane will want to climb with speed & you will have to trim nose down, but the trim change will be speed dependent -- a real pain. Plus there will be more drag & it won't want to fly inverted at all. It will also tend to balloon on approaches if you have to make a slight nose-up correction. Better if you actually learn to land it as-is.

A better alternative is to go whole hog & actually add flapperons, then the entire flight envelope won't be compromised & you can practice using the flapperons at a safe altitude before you actually try them out in a real approach.
