Short of raw SQL, can I query for multiple attachment metadata that have a given array key?

Compare two meta key values against each other inside the get_posts array?

You can’t do this in the meta query I’m afraid. You’d need to get all the relevant records in meta query, then make that comparison inside PHP, to filter out the records you don’t need.
