Have you seen these?
https://www.amazon.com/gp/product/B00AWR04HK/ -- Stephen King's The Stand Vol. 1: Captain Trips (Stand(Marvel))
That's volume 1 of 6. The next five are all on Amazon as well, and the series goes through the entire novel. They're done by Roberto Aguirre-Sacasa (author) and Mike Perkins (illustrator).
I bought them about three years ago and read them on a Kindle app. They're pretty good, and faithful to the novel. Be warned though, the illustrations pull no punches; for example, the depiction of Harold Lauder's corpse (discovered by Stu et al in the desert) leaves nothing to the imagination.
