I would be OK with Larian, I only want Mitsoda back. He made the first game the gem it is today.
I would make Wyll a Brujah btw. They are often idealistic and have a code if honour.
And Astarion a Toreador Antitribu. They use their love for arts mostly for perfecting torturing and suffering (not umsimlar to the Tzimisce), which fits perfectly with Astarion.
Lae'zel would also be a great assamite warrior cast.
My player characters are most likely all Malkavians.
Hehe, my BG3 characters are definitely Gangrel -- three Rangers in a row who like sleeping rough and can speak to animals, and, very soon, a druid.
EDIT: Wait, is Halsin the Beckett of Baldur's Gate 3?
