You certainly identified correctly one of the most important factors. But there are many others such as the chemical composition of the steel, that of the fuel, atmosphere control, `soaking' time and temperature. Metallurgy involves the successful management of quite a number of variables.

Now, would an European smith with comparable levels of knowledge and experience to a top Indian/Persian smith be able to create wootz/pulad ingots and forge a watered blade from European iron ore? Or is the precise mix of iron/carbon of Indian ore important?

Forging Damascus Wootz with the tell-tale surface pattern was considered a lost art until very recently. Have a read of that paper that I gave the link to in my post early on, No8 in this thread. It will probably answer your questions. One of the big problems, as I see it, is that we do not even have a clear consensus as to what we are talking about, that is what exact type of steel, forging and heat treatment we are specifically interested in. For my part, I am happy to settle for any pre modern crucible steel, but others apply a much tighter definition. For example, in the above link, one of the swords was declared not to be true Wootz Damascus because it had a lower carbon content.
Cheers
Chris
