I've thought of the opposite. Break the big skills up again and give out more skill points. My ability to lie doesn't help my lack of ability to pick pockets.The bigger idea was not just to pair skills and ability scores as needed, a variant rule that I have to say I'm the only one I see doing around here, but to trim down the skill list so everything on it was meaningful. Combining similar choices like Athletics & Acrobatics, and leaving them differentiated by the ability score. And folding little used ones like Medicine into other skills, again differentiated by ability score.
