I like the idea.

I'm not sure if its actually feasible. I suspect that its more complex than it seems.

I'm also not sure whether there are that many real use cases. Most of the time you control your exception hierarchy (so you can choose unchecked) or you have to live with a published API (the JDK) and so it can't be changed.
