Ehh, this doesn't solve all the problems in the park. Kidzone is still standing. We'd still have a SCREENZ problem (F&F, Ghostbusters, and Knight Bus would probably have screens involved). And with Hollywood RIP Ride Rock-It and Mummy gone, now we have a severe lack of coasters in the park.
However, that last problem can be easily solved, although some might not like it. The solution to the coaster problem would be to build a B&M Mini-Hyper where HRRR now stands. USJ has a similar coaster which is pretty much the better version of HRRR, and I think it would be great in this park. The coaster has forward and backwards facing trains and focuses on airtime, which is nowhere to be found in USO. It's smaller in height and better with capacity. Just an all-around better fit for the resort as a whole.
