Haha well as a person of Pakistani heritage I give my consent.
I agree in that appropriating other cultures in a more realistic setting (which may give the implication that this is how X people are) and getting stuff wrong can sometimes end up unwittingly insensitive, even with good intentions. But if you're looking for new words in another language I say its fine. People look for words in other languages all the time in fantasy (I realize I'm only assuming thats what OP is writing).
Actually this is done in real life too, words are borrowed from other languages alot and their meanings get distorted. The history of English is really interesting in that regard. OkaystopmebeforeItotallynerdout.
EDIT: btw that blades thing wasn't too bad. If you see yourself out be sure to drop the mic on your way.ji
