There’s a bunch of fantasy series I would want on this list. The anime style would lend itself well to various magic systems, fights, character and species designs, etc.
1. The Wheel of Time (Currently in Live-Action development by Amazon Prime)
3. The Stormlight Archives
…Honestly, pretty much anything in the Brandon Sanderson Cosmere.
The Dark Tower would be an interesting one.
I think the original John Carter source material by Edgar Rice Burroughs could also make for a good anime series too, now that any Disney franchise hopes are non-existent and the rights have reverted back to the Burroughs estate.
