I'd rather have teleporters or railways like in Mass Effect that were used to transition you from one place of the Citadel to the next. Or maybe just a holographic unit you could access like ME's info hubs.
Say you're by the speaker but need to decrypt plans from the shipwright. Go over to the holo-pod w/e and you can access "vanguard, shipwright, quartermaster, cryptarch" etc...And speak directly w/ them without having to run to go see them.
