It works. Project completed. :)

Note: if you want to run RH95 demo examples from the RadioHead library version 1.74 (the current release as of this writing), you will need to edit the demo code to make two simple changes:

1. Instead of:

int led = 9;

change it to:

int led = 2;  //LED is on pin GPIO2 of Wemos D1 Mini

2. Instead of:

RH_RF95 rf95;

change it to:

RH_RF95 rf95(15,4);  //Ra-01 chip select connected to GPIO15, and Ra-01 DIO0 pin connected to GPIO4

When I made those two changes, the demo code examples "just worked."

Starting with MySensors Release 2.1.1, it appears this LoRa radio is now supported by MySensors:
"New transport layer: RFM95 (LoRa mode)"

I just now uploaded a mysensors serial gateway sketch.
