The only thing about the "1 fan in, 1 fan out" method is that you're only moving the same amount of air that one fan would move.
E.g., if the fans are rated 110cfm then you only get 110cfm through the hood. But if you direct both in, or both out (and vent for the other direction) then you get 220cfm through the hood. Not saying it's wrong to do 1-in, 1-out, I have 2 hoods this way, but thought I would point out that about the fan directions because it is often overlooked.

I wanted to avoid a fan in the visible end of the canopy. Is it that much better to have them on opposing ends rather than blowing horizontally in and vertically out? If so I'll do what's safer. My wife hates house fires for some odd reason! The fans I intended to buy are these:
