Maybe you could mention it's secondary hull in a novel and clear the matter up !
From what you have written about other classes of ship being developed from NX parts it wouldn't be a stretch for there to be a family or generation of related ships in production - new versions of the original NX, refit style, Pioneer and maybe others.
