Oh no I didn't mean any -more- forward that they -currently- move to. Even moving as much as they do I'd expect it to get more pitch sensitive. It's one arm fully forward, and then the other arm moving maybe halfway back to the retract position and then forward again that looks more like a human waving than 'just' a retract wing. Yeah it might be cooler to make it wave further forward but the pitch-up and stresses would both be enormous and outrageous.
