IMHO that might be a bit too close to synchronous_standby_names.  But the
name might not be the only issue, as there is a separate proposal [0] to
add _another_ GUC to tie standby_slot_names to synchronous replication.  I
wonder if this could just be a Boolean parameter or if folks really have
use-cases for both a list of synchronous standbys and a separate list of
synchronous standbys for failover slots.
