I say sure, why not, except they should start on their own 10.
While we're at it they should change FGs to
1 point for FGs 33 yards and under, same as an extra point.
2 points for FGs 34 -44 yards
3 points for FGs 45 -55 yards
4 points for FGs 56+ yards
And all TDs over 50 yards are worth 7 points
After a TD you can go for the extra point, 2 point conversion or the 3 point conversion from the 15
And last but not least, safeties are now worth 3 points
