That will do it - but it also means that clients will change address mid-session - breaking any existing connections. For all the reasons that get listed when the usual variation of this question comes up, that's a recipe for "unhappy customers".

On a more granular level (ie requiring less than double the required number of addresses), you could do it with several pools and have (say) 9 out of 10 pools active at any time - that would just need 11% extra addresses. It would still have the issue of killing active sessions when a client has it's address pulled from under it.
