ND filter or reduce aperture?

Have you considered just using an ND filter?  Depending on the amount of ambient you want to kill, the ND filter could affect AF, however.  It might be a good work-around solution to achieve what you're wanting.

If you're wanting to sync at extremely high shutter speeds without an ND filter, like 1/1250 and faster, I think it's probably not feasible.  At 1/1250 in FP mode, your flash output is so significantly reduced that you need the flash placed just a few feet from your subject.  What is your subject type?

Killing the ambient is better done by other means.  Can you not just shoot at a smaller aperture and increase your flash output?  If you're wanting to keep a large aperture, then I think an ND filter is your only option to kill the ambient.
