Almost lost a wheel

I would determine the spline size of your 7/16 studs, left and right, front and rear (likely different f&r).
Then hunt up 20 new studs with the right spline size.... in 1/2"
i don't think there's enough meat in the drum hub to blow it out for a 1/2" stud

i mean, i've *seen* it done, and frankly i'd take adapters over that approach.

out back, i don't think it'd be a problem. or if he's running a 7.25 dr. diff sells BBP axles.
