No prob, there is a price to be paid for “bigger and better” just beware more rotating clutch mass generally means less reliability, more load on the drive train and CHP. What do you want to fail first?

For everyone else that does not always believe sales hype and think you have to replace your clutch here is a tip: Take the stock light weight casting to a professional(do not try this at home), preferable certified pro have them shot peen the mating surface to the belt to 125 RMS. What that will do is prevent a tension crack at the surface (which is how cracks occur and propagate) which casting’s are notorious for. It does so by putting the surface in compression, I use it as a disposition after mechanics gawl surfaces up from drills, grinders, etc. It’s a fine ceramic of different grit wheel 3M, etc. It should also improve the coefficient of friction, fatigue and thermal properties, belt reliability by allowing better heat convection from a more dense belt mating surface, you will then have a more reliable higher strength-to-weight ratio than stock and I’d bet after markets. Good luck!
