Can I just drill the hole bigger to take them or will I die?

I just drill them...finish them off with a round file, I guess there's a chance the rim could crack, but that's not happened yet.

I've drilled all mine. No idea why presta is ever used on MTBs.

Did a pair yesterday morning. 8mm drill and a little opening out with a warding file. Took about 15 minutes all in.
