If you get a texturizer/relaxer and put it in without backcombing it, and leave it on for like 5-10 min, it should still loosen the curl.
HOWEVER, texturizers and these methods can be incredibly inconsistent. If you try it, good luck!
P.S. I know it's your hair, and you can do what you want, but your curls are super pretty and if I were you I wouldn't touch them!
