Using an existing index, support building a new index on with a different collation on the same fields.
For example, given an index on {a: 1 } with a collation {locale: "en_US", strength: 3}, support creating a new index on {a: 1} with a collation {locale: "en_US", strength: 2}.
Investigate how to support this efficiently, if possible.
