Modernizing Arthurian Legend

With all the different takes on Arthurian legend in modern media, I'm surprised adapting the legend to a modern or futuristic setting isn't more popular.  Plenty of stories with more modern settings have Arthurian themes, but not really proper adaptations of the legends.

All the standard takes on Arthurian legend that define it for modern readers are done in a more (then) modern setting then the 5th/6th century setting of the original Welsh poems and the history that Arthur would have lived in.  The Grail romances are based on the world of the Crusades, and Malory's tale I've read before was largely done with the War of the Roses in mind (making it the Game of Thrones or Final Fantasy Tactics of it's time).

Of course admittedly those were not completely contemporary stories, there is still a sense of an age gone by in them.  Not unlike how people today often call the Second World War the "Greatest Generation".

Then it hit me as I was thinking of that, why not a version of Arthurian legend that is a Diesel Punk alternate history version of WWII.?  And it can draw inspiration from Indiana Jones type movies with the Nazis seeking the Holy Grail and the Ark and other relics, but I'd go with the theory of the Ark being in Ethiopia, and the Grail more directly modeled after the old Grail romances.  [Update, and you could maybe now take inspiration from the Anime Izetta The Last Witch].

I've created a list of Arthurian characters with roles they could play in this setting.  In order to make this work I had to ignore the Pacific Theater, this is focused on Europe, Africa and the Middle East.  And don't jump to too many conclusions about these identifications, it is an alternate history.

[Update March 31st 2020: I've made a lot of changes to this list over the years that includes many made today.  And more may be made in the future]
