That's a good way of approaching it! When it comes to shipping personifications, I've veered sharply toward "literalism" in recent times — though some of my very favorite pairings are ones rooted in storyline elements, compatible personalities and plain old "they would work well together" over any sort of real-world associations (See: SAGE/Multics, Unix/Linux and OS/360/MTS), so I should probably be more flexible in this regard. ^_^
Of course, I was planning on it anyway!
