Fan Casting Batman '66 Season Six Ideas

Season 6: Season Six is almost all about Batman on his own. Robin and Batgirl make appearances as supporting leads every couple episodes, but Batman is now the leading star. I'd have Aunt Harriet be made more of a minor character too, and I'd replace her with Leslie Thompkins. We'd still see Aunt Harriet, obviously! She's too good to abandon fully! It's just... we'll see her less, since Dick is at College (thus eliminating the need for her to live at Wayne Manor).
