The only other one I can think of at the moment is "Can the hypothesis be worded in a way that refers to only physical objects?"
See also this post: Making Beliefs Pay Rent (in Anticipated Experiences).
It could, if we say that consciousness (I'm still not sure how that word is thought of here) is thought to be a physical object. However, (and I am saying this tentatively), I've heard of instances where particles can be made to have no distinction, where action on one particle has effect on a particle at a distance, so there is a prior example of two physical objects being the same entity despite spatial and numerical difference.
This is a thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. The previous "stupid" questions thread went to over 800 comments in two and a half weeks, so I think it's time for a new one.
