My ideas:
- White Tree. Impuls set with tree and two Gondor guard knights in exlusive type of armor and helmet.
- Bag End. Bilbo house with Bilbo, Gandalf and Thorin minifigs.
- Rohirrim's camp. 2-3 minifigs with horses, tents etc.
- Grond. Huge battering ram which destroyed Minas Tirith gate with troll, orcs and Witch-King(in this scene he appears only in book) minifigs.
- Ithilien ambush. Few Haradrims ambushed in the woods by Faramir and his companions.
- Mordor siege tower. Nothing to add :)
- Bree. It would be similar to Medieval Market Village.
- Orthank. Saruman's tower which would include Saruman minifig plus some orcs.
- Black Gate. Big set with gate and two towers on both sides, one troll, few orcs and few Easterlings entering Mordor.
- Minas Tirith. In my opinion its theme for one huge set similar in size to Death Star set ;).
I think its great idea but i would like to see it without any additions which would make the price higher. I think Grond plus decent minifigs is enough.
