Hypothetically, assume ND and WVU were to join the ACC. Each pod would play each team in its own pod every year. Each team would also have a permanent rival from each of the other pods. Finally, each team in a pod would play every other team in another pod on a rotating basis (not duplicating the rivalry game from that pod). That adds up to nine conference games a year. Let’s say the pods were as follows:

ND
Syracuse
BC
Miami

VT
WVU
Pitt
Louisville

UNC
NC State
Duke
UVA

Clemson
GT
FSU
Wake

VT’s permanent rivals from each of the other pods would be: Miami, UVA, and GT. The remaining three games on the schedule would be the non-rivals from another pod, rotating each year.
