I would put them in bigger containers, so they can develop more root mass over the winter. That would be the advantage of starting them so early. Then when you put them out in the spring they would have a good head-start. I do that with my tomatoes and such, and people are always saying "holy cow, how did you get ripe fruit in May?!?!?" We usually can't plant tomatoes and melons until mid-May, and the ones I start inside in the fall are all blooming and ready to fruit the second I put them out. Makes me a hero with the neighborhood bees for about a month...
