Re: Basement - 24" gap btwn foundation and framing
There would be no advantage of introducing a vapour barrier with the method you are proposing. Besides, the vapour barrier wouldn't be toward the foundation side ( since that would be the colder surface.

I would cover the foundation walls with one or two thick rigid foam ( depending where you live ) -- frame the walls touching the foam and then finish drywall. This wouldn't require any additional vapour barrier -- the open stud bays would allow easy access for any future wiring --- and you would gain some valuable space.
If you do enclose the sump pit and it doesn't have a tight cover seal then you want to make sure the enclosed space has ventilation--- either louverd doors or vents. Otherwise you could end up with mold / mildew issues within that space from the humidity form the water in the sump pit.
