I say none from JK. Leave that to the modmakers.
However I think Jabba's Palace, Homestead, Throne Room,Cloud City/Gantry should be included, but remade more like the movies. I think they should focus on actual locations. Those levels were my favs cause when I was in them, it felt closer to home.
With the new engine they can make these levels look phenomenal.
That's not to say I don't want some new ones. (Jabba's Sail Barge, Theed/Generator, Ewok Village, and a ton more I can think of.)
