Just buy 'em. Look at the OX801d for a really spendy version (shiny, that’s it).
I have MikeD’s old 801d’s, they take shimano (and CK) standard BB cups, easily available 110/74 rings, easy to setup a mid ring for 90% of the time and a bailout little ring for climbing.
Narrower Q than the triples you were looking at too.
