We have a LEED NC project in Massachusetts (Office space with 2 residential units above). On the roof will be a PV system producing just over 50% of the buildings total energy consumption. The energy produced by the PV will be used on site in the office space by the building/PV owner, but all the SRECs will be sold. We are considering buying Green-e certified power to match 100% of the building's use. We would like to apply 70% to EA6 for max points with exemplary performance, and the balance (30%) to EAc2 to meet the double SREC purchase requirement, yielding more than twice the 13% max threshold. Would that be acceptable for both credits?

There is a LEED Interpretation indicating that you only have to replace the RECs at 100% to claim them for EAc2.
Assuming your building is all electric I think the math works but maybe a little differently. For EAc2 the solar production counts if the RECs are replaced. So if the solar is 50% of the total then you need to apply 50% of the RECs to the solar. For EAc6 it is based on the building's electric consumption minus the PV output. So again assuming all electric, if 50% is PV then you only need 70% of the remaining 50% for EAc6. Since you are planning to buy 100% of consumption, not including the PV, you should be covered.
