I got my answer, thank you.

You can transform a pet into a steamworks pet. c:

Oh, that's a relief. Thank you very much for answering!

You can make existing pets Steamwork. The only difference is that ones created from scratch will get a little gear-shaped gender symbol. But otherwise, yes, you can make Distort into a Darkonite just fine. :) [edit] WELL THAT WAS FAST. xD
