Do you think dnsmasq could watch/ping its IP address range while it is idle, caching the result? It might examine the local arp table as well: If there is an entry with matching MAC and IP address, isn't it reasonable to assume that the IP address is not in use somewhere else?
PS: I found https://tools.ietf.org/html/rfc5227 on the web. Interesting read, but probably it won't help to avoid the delay. I would agree that it should the job of the client to make sure that the IP address is not in use yet, and to reply with a DHCPDECLINE to the dhcp server. But AFAICS strongswan's dhcp plugin doesn't, and surely it is not alone. Will dnsmasq offer another IP address in case it receives a decline? Thanx anyway.
