Nah. Disagree with that on principle. Most characters aren't gonna react to who has the highest charisma just because it's convenient fir you. In fact, in RL, the lowest charisma character will often ruin things.
Also in dnd, if you interact with an anti dwarf racist with a dwarf in the part, it wint matter so much if yiur ekf has a charisma of 18. Sorry not sorry. And, many you interact with in bg3 including your party members, see your MC as 'da man' or 'da woman' so I'd argue 9o% of dialogues should be based on your MC's stats.
