Absolutely. For us it has worked well to separate the config into

dhcpd-server-specific.conf	 - Server related stuff (e.g. failover)
dhcpd-common.conf		 - Common config (e.g. pools)

where the server-specific stuff typically changes very rarely, while
subnets etc. are defined in the common configuration (same for both
servers in a failover pair) - which can then safely be scp'ed over as
necessary when it changes. And one of the files then includes the other.
