That's kind of what I had wanted to do originally (but have IMigrationProcessor expose IQuoter).
Unfortunately, it's not possible because IMigrationGenerator currently does not have access to IQuoter. We'd need to add a reference to the FluentMigrator.Runner.Core project in the FluentMigrator.Abstractions project.

Or move IQuoter to the FluentMigrator.Abstractions project.
Both of which are breaking changes.
