a problem with some centrelock style discs is that the connection between the aluminium spider and the stainless braking surface is made at a large diameter, such that the some brake parts (eg the tangs on BB7 pads) can foul on them. AFS discs appear to have a small-ish diameter spider so I think there is less likely to be a clash.
Provided the track width/diameter of the discs you use is correct, and you are prepared to adjust for any small differences in offset, I don't think you are going to have big problems.
