Most of the taxa in Chimeria were previously in hybrid classes, but I don't see anything wrong with your edits (although Agnaria was previously in Pelycosauria, so I've moved it back to there to make it less practically synonymous with Agnathasauridae).

I had previously considered making Agnatha a class of jawless vertebrates, because for a lot of them their jawlessness is more distinct than their vague resemblance to real-world taxa. However, even if I included Varkoridae (which isn't particularly arthropod-like, so could easily be removed from Hemiinsecta), there aren't many families to go in it. So I might recreate Agnatha in future if I can think of a way to deal with that, but Chimerae can remain dead.
