Sounds like you want RF == N more than CL == N-1. You could create a separate KS with RF == N and then just write at CL = QUORUM, the write will be sent to every UP replica.
For background: The System Keyspace uses the o.a.c.locator.LocalStrategy that *only* stores data on the node the mutation is sent to. So there is *no replication*, the system takes care of ensuring data that needs to be replicated (i.e. schema defs) are replicated via higher level features. Using the LocalStrategy yourself is probably a bad idea.
