Help-needed: Efficient/elegant technique for capturing connection variations in SysML

Looking for ideas on how to best model the following scenario.  Two configurations of a complex system differ by removal of single connector.  Goal is to minimize duplication of definition, while avoiding ambiguity.  I've tried 2 techniques: A) copy the lowest-level system that owns the connector; B) use a generalization relationship between the operational configuration and the maintenance configuration.  The "copy" technique (A) results in a lot of duplication of definition (undesired).  Whereas, the "generalization" technique might not accurately describe the scenario - although we don't need to show it on the diagrams, the LRU-LRU connector that was disconnected for software loading still exists through inheritance (also undesired).  Any help / ideas appreciated.  Thanks!
