"more than one way to skin a..." as they say ^
I haven't seen this style in person but if the stud have enough threading to grip (and be SAFE after modding) then sure: just reduce the end of the studs that intrude into the holder's interior!
I'd use a Dremel to grind them flat (or flatter) while leaving everything in place, maybe even adding a dollop of epoxy to what's left, for insurance.
You want your new brake pads to stay on and stay tight!
