Perhaps you can, I never tried it though since anything that mess with XP gain will have possibility of making the recording goes awry and gets banned. Instead, I modified the cat study from base upgrade to +50k level, that way any stage I played gives more than 1M exp sure shot (The last stage of latest SoL gives 19M exp per play not doubled by XP powerup)
