There's a lot more space behind screamin than people think (even more if they reroute the road).
I could see them possibly putting Ratatouille back there, or possibly a variation of Toy Story Land. TSL at HKDL is only 2.5 acres. TSL at WDS is only 2 acres. I believe TSL at SHDL is going to be 4-5 acres.
