well theres this or we just make the nacells longer and forget the whole extending nacells thing, cuz youve got a badass model here already

though i am gonna say as this ship is a very late 24th centurary / early 25th century vessel so by then id think that the way warp coils are design has been refined and because the smaller part does indeed fit inside the forward section on the nacell without hitting anything important id think its dooable.
anyways its your call on wether to keep the nacell extension or just extend the nacells in length and leave it at that.
just realised thats the wrong image save i uploaded, heres the correct one....
