If you don't mind using a couple of additional layers, you could:

* Have the LoRa transmitter send data over the air in whatever format (TNC2
would be handy, or maybe raw GPS sentences).

* On the LoRa receiver, re-format to TNC2 (if necessary) and send that data
to Xastir (same box or different box) using the xastir_udp_client tool.
Untested example:

xastir_udp_client localhost 2023 <callsign> <passcode> -to_rf  -to_inet
"KI4MCW-3>APRS,WIDE2-1:@123400z3730.55N/0773042W Comment"

...where <callsign> and <passcode> are used to authenticate into Xastir.

* Xastir maps the location and/or forwards the packet to the Internet as
desired.

More homework to follow, of course, but the wrapper script on the LoRa
receiver would be straightforward.
