The leaks happened in December 2014, while that debut trailer came out in May 2015. That's a whole six months; certainly trailers are not made that much in advance? I think it's just a coincidence.

Victory just seems like the working title to me. Aside from the blatant reference to Victorian London, "victory" as a word indicates nothing. Except for Evie and Jacob presumably triumphing over the Templars at end. Syndicate works much better because it relates to the gangs that plays a central role in the narrative.

As for the changed outfit, it might have been an early version (it looked a bit cobbled together from earlier protagonists tbh - the new outfit works much better). Things change during development, like the rope launcher which you apparently can't swing from now, even though it was depicted as such in the leaked screens.
