I think doubling-down on the Monk's half-arsed Asian-coded-ness (which is very much A Thing) is a bad idea when none of the other classes are particularly culturally coded and indeed have become steadily less so where they once were. The closest to being anything-coded is the Druid, but honestly, it's significantly less Celtic-coded at this point than the Monk is Asian-coded. The Cleric was once arguably pretty Christian-coded, but that's long since been washed and abraded down to nearly nothing, whereas the Monk is nearly identical, theme/vibe-wise to how it was in 1E, when it was directly inspired by the kung-fun movies of the era. All attempts at expansion have been sort of locked in a cage of "But it's basically a Shaolin Monk, right?!".
Which isn't to say that wouldn't be a good excuse to get some more diverse designers in (honestly any way to get younger + more diverse designers in is good), but I think going towards a more Martial Arts focus and away from a still heavily Shaolin Monk-inspired vibe would make a lot more sense. In fact I'd suggest a ground-up rebuild that just had the "classic" Monk as one subclass of many.
Won't happen because WotC are too concerned with making it compatible with old subclasses and so on, despite the fact that probably no-one really cares, but there we go.
