Here, try this one. It's a fusion more than a xover, and pretty AU but I really enjoyed it. And it ends TOO SOON. (AU SPN/HP xover; 9000 words; gen)
I also think that with HP xovers, sometimes people rely too much on "magic" being the explanation to what's happening. Even JKR doesn't do that, and she wrote the original! I like it when there's rules governing what's possible. Not because I'm necessarily a fan of rules but because making stuff work within rules is sometimes much much more interesting.
Oh I know EXACTLY what you mean! Read kellifer_fic! She can do exactly the same. There was this vampire one once, and she explained almost nothing, but the world was so vivid nontheless. And most of what she writes is gen, so that's right up your street. :D
I possibly have some Merlin recs around. Merlin was my fandom before SPN. There were some really good ones. I can link you a few if you like. :)
