I agree with MOK, for the most part. With a custom, you could potentially have what is essentially a curved rapier blade made, but it wouldn't be very accurate. The problem is that the blade would be very slender, very thin, and very long, all of which add up to a rather fragile blade. Plus there's the curvature; how would you even sheath it? With that said, your best bet with the custom route would be to have the smith make a hand-and-a-half sized shamshir. After all, it's got the proper shape, be it curve, style, or what have you; it's just wider.
