at first it sounds reasonable, but...

how do you know when the 'large' bucket is almost full because of a pour and
then rain rate falls back to 'light'?
in these configurations big and small buckets steal rate mutually and the end
result is anything but accurate. 
at least if you build the funnel that doesn't overload one small bucket, the
worst case scenario will be a delay in measure of pour rate (rate clipping),
but no error in total water fall.

a rain gauge for both, very heavy rain and very light rain at the same spot, is
a real challenge and most probably not solvable with a tipping bucket type.
