Piston Weights

Just got off the phone with CP Pistons. Their wrist pin weighs
61gr and their 84mm piston weighs 222gr. I'm guessing it's safe
to assume that circlips and rings weigh pretty much the same 
regardless of the piston manufacturer. So:

2mm over = 214 + 61 = 275gr + rings/clips
3mm over = 222 + 61 = 282gr + rings/clips

Anybody got something lighter? 

Because these are Busa pistons the valve pockets would be
bigger to accomodate the larger Busa valves but other than that 
is there any reason they shouldn't work?
