I actually like how GURPS handles Charisma. Insted of a score, it is an Advantage that grants you additional wealth and bonuses on Social checks. You can "buy up" the Advantage to greater effect as well, or "buy down" for bonus points.
If you want to keep the Cha stat, applying something similar to d20 Modern's Wealth system and have the PC's generate income based on their Charisma scores might be worth considering, too. Having PC's be able to access resources without spending their hard-earned gold (in the way of favours, NPC support, gear/magical item access) might be worth something to the right player and/or group.
"I can't swing a sword, but I can call in a group of mercs who can do the swinging for me. And you say you need a diamond to resurrect your pal? I may have a lead on such a thing..."
