Sounds like good idea to me ... +1!
(But im affraid i have seen something very simmilar around here!)
But dumping Int/Wis/Cha wouldn't affect their dialogue or personality the writers had in mind when creating them. Attribute scores would be disassociated from actual attributes and characteristics, a.k.a "bye bye, RPG".
Why would it? O_o
I mean it dont affect your PC, so ... the same rules for everyone. O_o
Also, i know that naming the ability score "intelligence" (and others too, but this one is extra specialy obvious case) kinda imply that person who have it low is dumb ... but that is certainly not how this works. -_-
I know that many people tend to play low Int characters as almost Neanderthal barely even able to give long sentence together ...
Personaly i find that the oldest hurtfull stereotype ever. :-/

You'd think that having both int and wis stats would clue people in on there being more to overall intelligence than just the int stat, though the naming certainly doesn't help. A quick examination of what the int stat actually does in 5e makes it clear it is the stat for a very specific subset of intelligence; what you could colloquially call "book smarts" and the degree to which the character is formally educated. This is also backed up by the class that uses int; Wizards. Arcane Tricksters and Eldritch Knights also happen to use Wizard spells.
Wisdom covers interesting skills that seem to be more practically applied than most intelligence skills. Survival v Nature, for example. The former is the application of the latter, though the application doesn't necessitate understanding it on an academic level.
A character with 8 int could be dumb, but they could also be someone who never had access to formal education. And a character with a high int could be pretty "naturally" dumb too, but also be someone who has a good formal education.
A funny observation from the Player's Handbook: Bruenor is the example character used to showcase how to build a character in the system and happens to be an existing character in the lore, being one of Drizzt's companions. He is the leader of a clan of dwarves, a skilled field commander and a master smith. He is also given an int score of 8 because every other stat is prioritized over it and he is described as being "a bit forgetful".
In short, the intelligence stat seems to only be one side of intelligence, the other part largely being made up of wisdom.
As for the topic itself, I definitely do think some of the characters need to have their stats rebalanced, Wyll in particular. The odd numbered values he and Gale has is likely a result of Larian building them as humans with standard array ability scores though.
