Can't you still have 128 tasks even without sharing pages between tasks? That is, one direct page and one stack page for each task, with 256 pages total in bank 0.
With sharing I mean, when you have two or more tasks of which only one instance will run, they can use the same direct page. Similar if you can statically limit the stack size of the tasks to a fraction of 256 bytes, you can fit multiple stacks on the same page with some work.
