My brother works in TV production and has made numerous indie films. He and some collaborators wrote a treatment for sci-fi comedy based on Kid Colt and the Marvel westerns of the 60s. He has pitched to Disney in the past and sold a few treatments (that they've shelved). But when they were trying to get a pitch meeting, he felt Marvel didn't seem interested in that time period at all. Which is too bad - I'd love to see a Marvel western.
He is currently re-writing the treatment to de-Marvelize it and pitch it elsewhere.
