I really prefer historicals to the LE dolls. I don't mind the friend dolls since that gives me someone from their time to play with. The hair would be different for these time periods too.
I would love to have a Pilgrim girl. Perhaps her family fled religious persecution and then terror of the Native Americans, but instead they became friends and helped each other to survive the wilderness.
My genealogy has taken me to Harrisburg, PA, and the history of that area in the 1730's is very fascinating. The only problem with the Pilgrim idea is that there would be fewer accessories available probably.
I would also love to see a 1964 doll. I graduated from high school that year and remember the "Camelot" era very well. I love the clothes from then. The assisination of JFK changed a lot of things for us.
