I'm not going to pull them all, as I do want to have some visible deflector systems, which means they gotta be in those blisters as you said, but I will change them up a bit.  I'm going to make them tasteful.
As for warp engines, I'm not going to go with the TMP look, at least not completely.  I haven't started on them yet, just been going over in my head how I might want them to look.
