Second - You can't just take the 1D4's (APS-H) Auto Focus and use it for a FF sensor, you'd lose a lot of the spread needed for an effective AF system. In other words the AF points would be confined to a shorter/narrower section of the sensor than they should be.
Do you have any idea of what you are talking about? My 1D IIN has the same AF system as the 1Ds II, and yes, the 1D has more AF sensor coverage than the 1Ds.
