Zero page/stack mapping

It's more a theoretical question.

Can zero and stack page be mapped in the same way X16 maps banks of RAM into 8K window in the upper memory? What benefits and complications can it give?

I see potential improvements in multitasking, like it makes the context switching process much simpler with much wider usage of zero page and much bigger stack.

The hardware does not support this so on the X16, no you can’t.
