I guess if the intent was to make the PAT make more a difference in games, it'll do so by about 6-7%. Kickers last season were around 93% from the 15 yard line, and about 99% with PATs. I don't think this will change the rate of 2-point conversions much, unless there is an unusual distrust in the kicker, due to injury or weather or just being really terrible. A better option would have been to move the PAT to the 1-yard line for kicks and 2 point conversions, but meh. They are also pretty conscientious nowadays about adding extra injury risk to the game (recent kickoff changes for instance), so I don't actually believe they want to encourage 2 pointers.
TBH they should just do away with PATs. Wastes everyone's time. Perhaps make TDs worth 7 and if you go for a (what we know as) 2 point conversion, you either gain a point for making it or lose a point for whiffing it. Call it the "extra point gamble". The conversion odds on 2 pointers already hover around 50%, so in the long run, most teams would score about the same number of points whether they went for it or not. But it would definitely encourage teams to try and devise ways to consistently convert those "EPGs" and score more points in the long run.
