You could also import the singleton rule from Monsterhearts, modified -- only one XP from a miss per scene. (But I wouldn't.)
You could also change the end of session move to give multiple experience for each question answered, along with extra experience from alignment, and that would make misses worth less comparatively. Then, just change how much experience per level you want. Just another possibility.
But again -- getting the majority of your experience from missing is, in my estimation, really cool.
Give it a shot once before totally dismissing it, I would posit.
