I'm working on a mod to make the perk system a lot more grand and in depth. (Think similar to tge sphere grid from FF10) It will include stat increases as well different abilities and skill buffs. There is, however, only one problem. You recieve a total of 81 perk points from leveling up. This new system will requite a lot more perk points to take full advantage of it. I plan on giving a player more than 1 perk point per level up, and reward them perk points for other actions (quests, dragon kills, landmark achievements, ect). This aso makes it so that capping your level does not end perk point gain (no more being stuck with only a few perks for you high end character). I've been looking, but due to my inexperience, I can't seem to figure out how to go about doing this.

So... the questions:

1.) Is this even possible in the editor as I've already ran into a lot of impossibilies already (custom actor values for example)?
2.) How would I go about increasing the perk points from level up to something like 5? (I'll balance out the best number later.)
3.) If scripting is used for the above question, would it be possible to us a similar script for rewarding perk points for other actions?

Thank you in advance.

As far as I've been able to find, you can't change the number of perks gained per level. Not sure if this is a hidden hard-coded function or what. Some people are using a 3rd party program for this.

I believe Falcone is correct - perk points are hard coded.
You either need to script the new perks to be automatically granted or you will need to make your mod dependant on the uncapper mod by Elys and SKSE.
I think you can add the the new perks in the CK and let the user choose which they want, but you will need to tell your users that SKSE and the Uncapper are required; and to change the uncapper ini to give X number of perk points per level. Keep in mind that according to Elys, there are a maximum of 255 perk points available.

There is already a mod that does this, however it's a SKSE mod. http://www.gamesas.com/topic/1287595-relwip-skyrim-elys-uncapper/
