I don't think pudding, once opened, is shelf stable. You need to check with the manufacturer or look on the label.
No cheesecake filling is shelf stable unless it is completely fake. No pudding, cheesecake filling, or ready-made cheesecake will work.
It will have to be shortening or butter and the cheesecake oil. Those oils have a very chemical, unnatural taste, but that is your only choice.
Edit: I forgot to mention that the powder mix in something shelf-stable may work, but make sure that the powdered pudding, once wet, does not need to be refrigerated.
