It would be a critical theory book, blending close-reading semiotics a la Barthes' "S/Z" with cultural-studies riffing, about the Lee/Kirby run of the Fantastic Four.
I can only think of a few problems with this:
1. No mainstream publisher would touch it, because it has zero commercial potential and lacks a certain popular resonance.
2. No academic publisher would touch it, because it is about comic books and because I am a high school dropout.
3. Even if someone published it, no one would buy it or read it.
Other than that, I think it's a pretty neat idea.
