Yeah, I think not. You completely fail to explain how what you propose is correct. The thing is; we rely on static objects because they provide persistence. Their address will never be re-used. Dynamic objects do not provide this same guarantee. And when you re-use the key address for something else, you'll mix the chains and things come unstuck.
