Those are two good ideas. For me, like I mentioned earlier, a 12 Grimmauld Place would be amazing. It would be open-faced on the back, and it would have the kitchen, a bedroom or two, an entryway, the drawing room, and Kreacher's bedroom. Of course, it would include Kingsley, McGonagall, Sirius, Lupin, Snape and Kreacher. Other possibilities would be the trio, Fred and George, Dumbledore, Buckbeak, Mr. and Mrs. Weasley, Moody, and Tonks. Also, I would like it to be a large, $100ish set.
