I'm working on a system to introduce advantages, disadvantages and quirks into 4e, ala GURPS. Basing it off the 3.x incarnation of flaws, I've come up with some preliminary ideas I'd like to throw out into the fires of creation and see what gets flung back 
Traits would be a very simple system of 1 for 1. You choose two skills, one gets a +1, the other gets a -1. Add some flavour and voila! Instant trait. I figure allowing up to three of these per character is about right.
Players could just make up their own. A +1 to Endurance and -1 to Diplomacy, for instance, could be called, "Dwarven Negotiation." Allow people to be creative and imaginative with them, I figure.
Boons and flaws are similar in that they're one for another. You can choose one flaw at 1st-level and that gives you a boon. Boons are simply feats, whilst flaws are 'anti-feats'.
Basically, choose a feat and create it's polar opposite. So Improved Initiative becomes Lazy Fatarse, ie. -4 to initiative. Obviously you could only choose feats to be made into flaws that actually matter. You couldn't, for instance, turn Linguist into Dumbarse.
Thoughts?
