I think a live action akira would be ridiculously hard to pull off and it being well received would be a pipe dream. Think about it
What are akira (anime movie)'s flaws? What are its strengths?
The movies main challenge was that they had to adapt a full manga series which is fairly long into a 2 hour experience. People may not catch everything that happens in 1 sit through since they had to keep things trucking along. A lot of manga stuff had to be cut. They cant do what a lot of movie adaptations do and cover 1 manga arc as it wouldn't work in akira. Live action wont help this since the same time to work with
What made the animated movie big was the presentation value, animation quality, and themes of the movie were groundbreaking at the time and greatly impacted anime after it. A retelling could easily mess up the themes and the other strengths would also be gone.
