You were asking for suggestions and I have two:
1) SCART support, so driving a TV with RGB Scart (An maybe NULA Support too).
2) Real Keyboard support. This may be harder but hoglet did connect a 3.3V modified Beeb keyboard to the Altera DE1 Beeb FPGA in the past. I can try and dig out the startdot thread if it is of interest.
With these two things, it should be possible to replace the PCB in a Beeb with a a Pi Pico! This could stop a lot of Beebs from being lost to the world.
