I'm glad you like it! 
I've also thought about doing that in reverse; using a high point buy (42 or more) at 1st level, to boost survivability at those difficult lower levels, but then subtract 1 point from every stat every 4 levels. To make high level games less overpowered.
I think my players would kill me if I tried it, though.
If you are looking for neat variants, you might try having the characters reroll their hit points every time they level up. If there new total is higher than their old, they keep it. If not, they keep the old one. It helps compensate if someone rolls poorly early in their career. And it's fun rolling lots of dice. If you go for point buy, then the reroll hit points variant will make up for all those 4d6 drop lowest that they didn't get to roll.
