Its the JJVerse, He can change the design however he wants and can get away with calling it anything
ooooh boy, i can see where that would take us... modders will now start making all sorts of weird and backward-looking strange designs and kitbashes of current ships, all to be called "JJ-verse" lol
how about a JJ-verse Galaxy, where we'll put the Engineering section off to the left of the saucer, slap on a Nebula weapons pod on the bottom, we'll put the nacelles on top and voila! lol j/k
