I believe you can add them dynamically via OMAPI - never done it myself.

Another way to avoid outages would be to run two servers. You can 
either use failover for a shared dynamic pool, or you can have each 
server offering one of two smaller dynamic pools, or have only one 
offering dynamic addresses. For static addresses, you can have any 
number of servers as long as they share the same static assignments. 
You could then restart then separately - giving the first time to 
come up before restarting the second.
