All the great engineers are anagrams of muppet names, IIRC.
It looks like you are correct, sir. These are the ones I found:
Milana = Animal
Zoot Ghent Gear = The Great Gonzo
Ethel Agames = Sam the Eagle
Xienwolf, if you want to keep the Muppet theme for the Great Engineers, this makes it easy since appropriate quotes can be found by looking up the characters (once the rest of the anagrams are deciphered).
Zoot Ghent Gear: A male of an unknown species. Known facts: Likes flamboyant devices. Romantically involved with a chicken.
Quote: "I shall now defuse this highly explosive bomb while simultaneously, and at the same time, reciting from the works of Percy Bysshe Shelley".
Ethel Agames: Male Avian Overlord. Known facts: Pompous. Naked under his feathers.
Quote: Why, did you know that underneath their clothing the entire population of the world is walking around completely naked? Is that disgusting? And it's not just people, although goodness knows that's bad enough. Animals too, even cute little doggies and . .. .. .. .. . cats, can't be trusted. Underneath their fur - absolutely naked! And it's not just the quadrupeds either. Birds too - yes, beneath our fine feathers, birds wear nothing! Nothing at all. Abs... oh m... could someone, hand me a robe?
Milana: Male Known facts: Loud, dangerously uncontrolled. Likes beating on things.
Quote: Milana! Milana! Milana!
