Going with your "_____ the Great" theme a bit, Catherine (the Great) comes to mind immediately

Raven's NMSAA, especially for a boy, but if you both love it, that's great. It's hard to find names you both agree on, I'm sure. Raven doesn't give me the best associations personally, what with the poem by Edgar Allan Poe and the former wrestler. It also resembles the word "ravine" (a gorge or valley) to me, although that's obviously not a big deal.. just my first thought
