I use Campags 80's MTB derailleurs and Cranks with sun tour friction Bar end shifters
I come from an era where shifting was something you did, not something you bought, removing the skill requirement .
Look at J tech cable pull adapters for RD swapping and mixing.
NB: Pauls Is releasing their own Road, short pull, cable Disc caliper, just now.
