Now I *know* it wouldn't be super in-character - but the idea of a Greenskin curated museum that manages to cow Da Boyz into thoughtfully observing recovered relics, inspiring lots more 'special greenskins' and Hero units to form... well, tbf i guess the same sort of vibe could be reached by a local tribe of greenskins making a pilgrimage to whichever museum we choose.
'Oi, we'z iz cull-churd skollers, you gitz!'
The idea of an entire waagh seeming powered by an interest in pottery rather than like, fighter planes or whatever, sounds excellent fun
