I googled yesterday, that
a). it is still on ESP8266, so flashing Tasmota is possible,
b). You can't flash "Portish" to companion MCU, but You CAN do a hardware mod, with 2 resistors, connecting IO pins of ESP directly to RF transmitter / receiver.
Find photo with 2 resistors in this thread:
https://community.home-assistant.io/t/new-sonoff-rf-bridge-board-need-flashing-help/344326/17
That's one approach.
I've made same to V1 and it worked! It is not as elegant as flashing new firmware to MCU and doing no HW mod, but works too.
The other one could be(!!) to leave original firmware, and then connect to link between ESP and MCU. They MUST communicate some way to make this work as it works.
Could be even easier if they use I2C instead of serial (do they?).

It seems to use serial for comms. Portisch allows you to ‘learn’ codes from an existing remote which I’m not sure if your mod does.
The R2 is mentioned here
Sonoff RF Bridge 433 - Tasmota
But it’s not clear about the Portisch

You (and that blakadder page) are partially right.

If you check on Blakadder
You will find the answer is no.
