Guess it depends on the skill tricks. The ability to spend extra skill points on cool bonuses is one thing, but on the other hand some of the skill tricks were like equipment trick where you just couldn't do something without sinking the points. Another thing about skill tricks is that they help everyone with skill points, not just rogues.
I've already done this for my upcoming King of the Giantdowns campaign.
They're called perks, however, and are specially tailored for the E6/Kingmaker/Birthright/Mythic(ish) clusterbleep that game will be.
