Well, FWIW, your first bullet below (reliable DMR, EchoLink, APRS network) REQUIRES the public Internet to work at all, both outbound AND inbound.
You could run HBLink3 as a private (on RF) network for DMR, and APRS can simply use AX.25. DMR coverage would be limited to the independent RF network (unless there was a bridge to an Internet based network), APRS subject to normal digipeater hop counts.
