I wont judge if it's overpowered or not. I'm not forced to use it so why should I do anything but help you make it happen.

In Fallout, there was a simple setting that altered how often you got a perk, so I would assume there should be a simple setting in Skyrim to alter how many perks per level you get. Though, I'm not sure about setting the hard cap to 50. I don't think they set an actual number, it just ends when all skills hit 100. Although, I could be wrong. We will have to wait for the CK to see on that one.
