Hmm, I don't know what a L2 shared medium is. More important: as long as switching IP addresses break connections, subnetting WiFi APs is really bad. So what we do today is setup our multiple home WiFi AP networks in the same subnet, same broadcast domain. Handover isn't great, but it works. As long as we don't bring in a WLAN controller or alternative, what is our plan?
