I like the concept of Toy Story Land, I really do, but this is Disney's third (or is it 4th?) time trying to get it right, and they can't even do that. It should have an area like HISTK playground for starters. That's literally one of the easiest things to do. Then add a (decent) Slinky coaster, and another flat ride that doesn't have too much of a height requirement. Move Buzz Lightyear over (retheme it slightly, use the framing narrative of Hamm & Rex playing a video game) to be near TSMM.
The imagineers would have to commit to scale though. No M&Gs in the land itself. Maybe when people exit, there could be one, but Woody, Jessie, and Buzz shouldn't be the same size as guests & Green Army Men if scale is really a large part.
