I've never tried this approach, but it seems plausible.  The link may be pay-walled, but the gist is to evolve fancier operators using masking of the genome.

Exactly.  And even though we're conflating the model of evolution with the real thing, I find it difficult to believe the "space" operated on by evolution is entirely convex or even connected.  So, (point) mutation alone may *never* reach some regions, regardless of infinite individuals, infinite generations, or infinite space and time.
