You could do some of that with labeled USINGs.
Perhaps, but not enough to handle the requirement. When you are combining two (or more) programs, frequently the labels will have duplications, not just the variables.
Back in the MVT days, SVCs had to be chopped up so that each load would fit into a transient area. With later systems, the requirement for built-in TTRs to subsequent loads has been removed, but except for the ones completely rewritten, there are still multiple modules that could and probably should be combined into single modules. For these, the variable names in the overlays generally refer to the same fields in control blocks, but the labels conflict. While there are some SVCs that should not be combined (SVC 34 comes to mind), some such as 19/22 might yield enough performance improvements to justify the work.
