I like your ideas.
Or make the PAT substantially more difficult...maybe from the 40 yard line.
Ditto. Great idea. Move it back to where the PAT percentage is 60%.......
Funniest one I heard about was making the player who scored the TD attempt the kick.
Make it like rugby football, take the kick from where the ball crossed the line; example - if a touchdown is scored close to the corner then the kick is taken from over that side not right in front of the goalposts.
