I'm all for a refactor of the scoring strategy. A single interface
attached to the index that takes care of it all.

Of course it is.

That I doubt. I have no deep knowledge of the scoring mechanism, but the
current classes are heavily couple by how the boosts work. It would
require a huge amount of deprication.

I would start with creating the new interface Index, inherited by
Directory or any other top level index implementation.
