In this case I take it that we can still have more than 3 servers as
long as only 2 of them are setup for failover, and only the failover
servers serve the pool.
This might not be an issue if I can get dhrelay going.

Yep, this is handled by the php code and the database, which has a flag
for dynamic or static, and will only write out static hosts if marked
static.
