Within a single point area there are may be wanted and unwanted targets, and I think by cutting green sensitivity I can swing the chances in my favour.

I doubt that the single point AF relies on (or effected by) the color info. That would be very annoying for cases where you want to nail the precise focus.
But rather than the color, the size of the target which is projected to the AF sensor cell is definitely important here. The size of the subject should not be smaller that the AF cell on the AF sensor. And these AF cells usually are not as big as they seem on the VF... Also their type can be different (e.g. D700 has 51 focus points but only the center 15 points are cross type).
But I'm afraid you've already eliminated these factors and I just sound like bla bla bla <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />....
