As I've said before, connecting those sections is a much bigger headache than people realize. All of that delivery access space would need to be rebuilt right behind that guest area, that space can't just be removed, it has to be recreated nearby (and it's pretty tight for fitting and turning around as many as 3 semis at once as it is). Then, you'd have to have those delivery shipments crossing through that new guest area to those major kitchen areas, all during guest hours. That's not acceptable show at all. There's really only one good solution that doesn't involve serious operational impact or completely rebuilding locations for services and departments that are using that area nearly 24/7; an elevated walkway connector, which has plenty of issues of its own (has to be tall enough for semi clearance, ADA compliance, themeing issues, etc.).
There is underutilized or completely unused space in the park that could be transformed. This space, however, is not part of that.
