My thought were to have two standalone dhcp servers. No failover, no
omapi. I would then rsync/scp the reserverations to the other when I
make changes.

Of course this means, the leases on each would be different, and that
is my question. What would happen if two identical dhcp servers with
identical reservations offer the same IP's?

The motivation would be to get a simple two dhcp server setup without
using the builtin failover.
