I'm just hoping it's eldritch exraterrestrial monsters...

Alien monsters could kinda work in MH as MH kinda broke the no magic rule a long time ago (multiple times), but this simply doesn't work as humans casually transforming into Rathian's and Rathalos.

Mi Ru's shapeshifting abilities work as it still retains it's body but changes in physical appearance and attacks (plus a cool theme).

An extraterrestrial elder dragon with a completely unique body structure and crazy abilities such as consuming the ozone layer would work pretty well.... Monster + human shapeshifters on the other hand? Don't think so. I'd guess they'd have a more justified existence if they had a true form.

I'm assuming it's just the thought process of anime girls transforming into Kut Ku's.
