I've just implemented this into a branch that mirrors the trunk
https://trac.nci.org.au/trac/cable/browser/branches/Users/mgk576/trunk_c3_c4
I've carried out two tests:

| by yxw599Two revisions of CABLE: revision 3623 and 4014. Revision 3623. calculate the weighted parameter values using C3 or C4 area fractions
Revision 4014: calculate parameter values for C3 and C4 separately, then combined them using the area fraction.
Tests done by YPW in 2017 found that revision 4014 conserved the carbon and water fluxes when C3 fraction varies from 0 to 1 (or C4 fraction varies from 1 to 0), whereas revision 3623 does not, because of nonlinearity of the combined equations for leaf stomatal conductance, leaf photosynthesis and leaf energy balance.
