Elder Scrolls Legion ranks

So, one of my players for the Elder Scrolls Conversion Project wants to play an Imperial Battlemage, and as such a member of the Imperial Legion. Now, I wanted to find a rank suitable for his character, but I wasn't really satisfied with the ranking system in Skyrim, being only 5 ranks in the legion, and the Morrowind ranks are just silly, I created my own, lore-friendly ranks. You can find them below.
