Nothing wrong with adding a little something to a scenario or setting though I often prefer to use Occam's Razor in most cases.  The last time I played my Macross vessel I gave the ship a pair of Cyclone mechs from Robotech which is decidedly non-canon.  I also added electric roller blades to the special forces team.  I mean, it sounds stupid until you remember that these guys are running around on foot beneath the feet of sixty foot tall robots!  The electric roller blades helped them avoid getting stomped on.

One thing I should add is that even though I'm spouting out technology, facts and the like, it has nothing to do with critique.  I just find the ideas fascinating.  I just love how Star Wars is so low tech!  It's cowboys and samurai- in space!  It also solves a lot of story problems that other franchises have.  Star Trek, for example, nearly always faces a problem that could be easily solved by some sort of technology they stumbled upon a few seasons ago but everyone conveniently forgets.

I should add that almost all of science fiction actually flouts science!  For example, even if a light saber was possible nobody could hold it without losing their arms.  The heat that thing would produce would burn anything within a few feet, including the handle holding the lightsaber itself to ash.
