Is it possible to convert an iphone 11 to an original iphone 12 housing?

hello, i was wondering if its possible to convert an iphone 11 to a scraped iphone 12 housing? i have an iphone 11 laying around, i was just wondering if its possible to do so or not.
i have seen some websites selling the housing separately but im not sure if it will look like a genuine housing or if its a cheap knockoff just made to fit iphone 11 internals in it and look like an iphone 12 from 10 meters away
