tokolosh, it seems I just adopted the cat you want, my Tessa. Sorry, I'm keeping her! I know what you're saying, you want a certain cat that 'acts' a certain way. It also seems you're also aware, with cats, you get what you get!
Good luck with your new kitty/cat, no matter his/her personality I'm sure you will love it just the same. It seems the only way to get just the cat you want is to have a few. All three of my cats have different ways about them.
