I fully agree with points 1-3.
For the persuasion however, the situation might be a bit more complicated as different characters might have different dialogue options, and the persuasion options themselves can be coupled to a primary attribute (convince somebody with strength rather then finesse, maybe even character specific options?).
I do however want to point out that I like Larians approach of differentiating between skill points for primary attributes, fighting attributes, social etc. This way, I have less of a feeling of loosing fighting stats by giving my "navigating" character some soft skills.
Still, I think some changes in part one like the shared lore and magic pockets really improve how the game feels, and unless there is a really strong reason to keep soft skills on individual characters I would always prefer the option that offers more immersion and less window management.
P.S:
Talking about convencience option, it might be nice to have the option of a shared inventory. While assigning weapons, scrolls etc. to characters does of course have a relevant purpose, buying and selling is made a bit annoying, as the OP already pointed out.
Maybe there could be a different view in the bargaining window, that just shows all items of all characters at once, or you could have a dedicated shared inventory where to put stuff you only plan to sell anyway.
While looting, you could then have to option to put stuff "on the pile", and the pile is accessible for all characters during trading.
When looting, you would then assign specific items to the characters that can use them, and then with one click throw the rest "on the pile".
The pile would have a size limited by the sum of all members inventory space combined (as that is in reality what the size is anyway).
The pile could be used in a similar way for crafting, as there is no reason to assign all the wood and toes to a specific character besides his strength (boring) or because you might be able to save 2 clicks when crafting later (boring).
