I was hemming and hawing over putting such thought into the post. I settled on alliteration. Truth be told, I just wanted to work in menagerie.

So how would you narrow a search for words containing a high number of M's? How would you eliminate the most obscure and unwieldy? Would you even want to? I think it would be more useful to somehow narrow a query until you have a ~100 word vocabulary from which to cherry pick from at will. You could assign metadata to them referencing common synonyms, and then substitute at will.
