Read my reply to the other poster, i answer exactly this. Actually test it yourself. Stop theorizing. I tested it. It works exactly as I said.
I think i know where you're confused. There is a firewall whitelist on the VPN endpoint route. Also it's impossible for the DHCP server to push a route more specific than this since it's a /32 route, so it's unaffected (together with the firewall rule allowing it) by anything the DHCP server attempts to do.
