Sure. It's done all the time in embedded devices that include an
Ethernet switch. One port on the switch has a "reverse" MII interface
that connects directly the the microcontroller's MII interface.

Not really, all the examples I know of are proprietary.
Just take out whatever code you have that's trying to talk to a PHY,
then configure the microcontroller's MAC to 100M Full-Duplex (or
whatever you want for the link), and you're done.
