I'm always in favor of balancing "dump stats" to be less so. Getting an extra proficiency per 2 points in int sounds a bit strong, maybe per 3 points? Also you should lose a proficiency for an int score of 8 or 9 >:)
And/or a lot of dialogue checks could use Intelligence Persuasion skill checks instead of Charisma persuasion checks. That'd be cool to see.
