Reviving an old thread, but I did end up building one of these for the Logitech Unifying Receiver. Also works with some cheap dollar store wireless mouse I had too.
Used the same mini USB-A to C adapters linked above, and modified the 3D printable expansion card design to hold the adapter and stripped down USB dongle. I can provide the step file if anyone is interested
