It won’t work as there is no you remaining to age, die, and leave bones for you to find.

What you need to do is travel back in time, stop your past self from doing the same, and THEN going forward in time to get your bones.

It could work. You’d just have to make sure to know when and where you will die. Then you could take your bones go back in time and die where you are supposed to.
I guess it depends on the time travel model at hand.
