TOS had a few "alternate engineering" sets, too: constant, gradual redresses of the main set, a surprising dilithium regeneration room, the odd nook or cranny that didn't fit the bigger picture unless you assumed it was "somewhere else". Entire "engineering decks" were occasionally referred to as well.
Underlying this all were two plot references to the place being a maze where one could set up a condo complete with a pool and a squash court and remain undiscovered until an opportunity for secretively leaving the ship presented itself. Forget about engineering decks - "engineering hull" apparently should be taken literally, too!
Which means there's very little problem with fitting every piece of engineering ever seen on screen for a given ship into that hull simultaneously. At most, we need to leave a bit of space for the shuttle facilities - and in the Kelvin movies, those were seamlessly integrated, in ST:ID without as much as a single solid bulkhead between the two different areas, even.
