What you describe in this part of your message can be done with no forks
whatsoever and I think that this is enough. Don't really see the reason for
any change in funding.
The idea of sending out a block header is essentially what I called
"optimistic mining" and has been described in more detail in my blog here;
http://zander.github.io/posts/Innovation%20-%20OnlineScaling/
The video explains with graphics too...
You may find this interesting :)
