Swapping CDI boxes

I just drug home a beat up old Suzuki 4-wheeler. It's an '85 LT250EF, four stroke single. It's missing the CDI box and there aren't any available for a decent price on Ebay. I think this quad will run if I get a CDI for it, so I'm wondering how feasible it would be to swap a CDI from a different model onto it. I imaging that the variables are initial timing, total timing, and the advance curve. I don't know any of the specs and I don't imagine that they're be easy to find.
I wouldn't think that the timing would vary much between different models and sizes of 4-stroke Suzuki quads, would it? Would it be doable to swap a CDI box from maybe a LT185? They're pretty similar other than their displacement.
I know that there might not be anyone here that knows about these quads, specifically, but how about just general CDI swapping. Is it something that's commonly done, and is it usually sucessful?
