Maybe roof beams?
Despite the possibilty the only ones so far seem to be in abh and wh40k if I remember correctly (not counting tractor beam as it´s vanilla).
Possibly a larger reactor (3 by 3 or more), obviously it shouldn´t just be an upscaled version, but it could possibly have restricted access points and be armored for example, or a 2 (or 3 if proxy parts are added) part high yield reactor core consisting of a center part and outlets. similar to but not the same as the wh40k reactor.
(Sidenote, if you consider the reactor parts tell me at some point, otherwise I´ll probably make them myself for another mod at a later point.)
