How difficult would it be to create a adapter that would allow you to use a AF-S lens on a F3 or F2 for example. Even if its just wide open or nonmetered? Is it impossiable for a mount to just attach to the camera and then the lens that holds the Fstop wide open?

You wouldn't be able to focus at infinity if the adapter moved the lens away from the sensor. If they mount on the camera (and I have no idea whether they do or not), you might be able to put a little tape on the aperture lever to hold it open at the aperture you're looking for.
G lenses I'm assuming - The few I have tried, mount fine (as all Nikon's do after 1959-i think that is the year), focus manually and the aperture is wide open. There is no way to control the aperture on the G-mounts since they are electronic. Depending on the meter on the camera it will probably meter but I'm not to sure how well.
If I may ask, why with as many cheap manual lenses out there on ebay why would you not just one of those? I got and old 50 f1.8 e lens for $20 and a 135 f2.8 off brand for $15.
I am about to buy the 85 1.4 and 35 1.4 this winter and would like to see if I could use those wide open in some cases. I wanted the afd version but I'd rather have the newer released. I do have a 24 2.8, 28 2.5 and a 50 1.4 for my F3. I just was curious if there was just a simple fmount to put on you could adjust the aperture like with older lenses.
It is all electrical. I bought an old N75 and keep it around for the instances I want to shoot some film. I think I picked it up on ebay for $30.
I have never seen and do not believe any adapters exist that control G apertures.
