I think the only potential downside is the one that the OP raised as his question, mechanical failure of a clutch drum that has been cut to resemble a swiss cheese.

Very unlikely he would have to take that much metal off to get a decent balance.  So agreed, no downside, other than his own sanity, fitting, spinning, marking, milling and repeat.

Or, he finds it oddly therapeutic and is unable to stop!
