My OP was written late at night and was thinking out loud. The next morning I tried to delete it. But a couple of replies bought useful clarification to my thinking.
Although my goal is simplification, the JC-1s with the Reference 1s would add only minimal complication. The 205 is already used in the room with a Sony HT A9 surround system, and a pair of JC 1s along the wall would be an attractive addition. Who doesn't like to see a pair of JC 1s?
