Can I change the configuration of the F-Series cluster box unit mailboxes?

No. The F-Series Cluster Box Unit mailboxes were designed by the USPS. The USPS owns the patent on these mailboxes and does not allow ANY modifications to them whatsoever, including eliminating, re-sizing, moving or adding mailboxes, parcel lockers or outgoing mail compartments.
