That's one, but I'd say she could use a decent Charisma score as well. I'd suggest swapping Strength and Dexterity. This would also make her a bad melee combatant, which gives her a weakness to counterbalance her strengths.
Regardless, a more complete solution (shich does not exclude the aforementioned) would be to either allow you to customize the starting ability scores of NPC partymembers, or making available some limited form of reassigning or redistributing ability scores. That's my take.
