Many moons ago, Monty posted a picture of his work computer on Twitter while he was transferring files he had been working on while away from the office. Specifically, characters he was working on.

Willow Schnee was on that list; along with a number of others; some we have seen, some we have not, and some are speculated to have been alterred or dropped. (Cobalt > Kobalt being the biggest one I can think of off the top of my head.)
