So you'd want to calculate how much this idea would affect the overall roll resistance of the boat (i.e. Is it worth it? Is it possible to add enough weight to make a difference?) and how would it affect the boat's recovery from a capsize/knockdown (i.e. Is it counterproductive?) There are probably more issues.
That was exactly what was thinking.
I seriously doubt that hoisting an anchor to the top of the mast in a storm will help prevent a capsize.

I was thinking in perhaps a very specific environment. Maybe in a wave-less anchorage that has a ferry going by every hour. Maybe a little weight aloft would dampen the periodic slop from the ferry.
Not sure it would but that was the type of scenario I was thinking of.
