NFL extra point rule change proposals

See article below about a proposal by the Colts, as well as another idea by the author.

My idea, which is not new (ask SWMNBN), is that during the touchdown play, the ball remains live, as in rugby, so if the ball-handler touches it down in between the hashmarks, the extra point attempt is tried just as it is under existing rules. Touching the ball down includes being tackled, at which the play is over, as well as the player's deliberately placing the ball on the ground. The ball has to be firmly in the grasp of the scorer's hand when it touches the ground, otherwise it will be ruled a fumble and the opposing team can seize the ball and score a safety. Recovering such a fumble by the team which initiated the play results in a touchdown, but the subsequent extra point attempt must be attempted outside the hashmarks as described below.

The ball's position specifies the lateral spot of down, not the player's knees or beltline, as when determining ball placement in regular field play.

If at the end of the touchdown play, the ball fails to be touched down in the endzone (player scores according to existing two feet inbounds rule and then goes out of bounds), or touches the ball down outside the hashmarks, then the extra point has to to be tried two yards further laterally to the outside of the hashmark at current distance or, (team's choice) on the hashmark ten yards further upfield than the current distance (hashmark the same side as where the handler either went out of bounds or touched the ball down outside of the the central part of the endzone).

Ball handler can't reenter the endzone from out of bounds to touch the ball down, but a fallen untouched player who scores without the ball touching the ground can get up to attempt to touch the ball down in another (presumably central) part of the endzone. The play remains live after partial tackles in which the player keeps the ball off the ground, is able to break tackle and able to rise back onto his feet or knees to attempt a touch down in the central part of the endzone.
