Yes, I have a similar sort of approach, I have a LAN DHCP/DNS server
running dnsmasq on a Raspberry Pi.  Dnsmasq is flexible enough that I
can configure around the quirks of the mix of hardware (Android phones
and tablets, some MS Windows machines, a DECT base station, etc. etc.)
such that everything works and has a sensible name I can use to 'see'
it.
