I set out to create a "simpler HTTP" once. Ended up concluding that by the time you've added the basic features, you need most of what a minimal HTTP request gives you. There might be some marginal gains to be made, but it's simply not worth it. HTTP is too good.
Commenting on this proposal directly, I don't see how a stateful protocol could ever be simpler than a subset of HTTP/1.1 with range requests.
