To name a recent example: Final Fantasy 7 Remake has a RTwP combat system and over 4 million copies have already been sold (it is a timed PS4 exclusive, so expect that figure to rise). Those are dream numbers for Larian.
FF 7 is nothing like BG. FF1 classic was turn based and sold well. Why not copy all every aspect of FF? Instead of creating your character, you will have to play as a androgynous teenager with a oversized sword. No race/class/alingment choice, you can only play with male 13 yo human fighter specialized on "ridiculous unpractical sword". Also, keep in mind that the console market is completely different than PC market. There are just no in depth RPG for consoles.
Just see the classic CRPG's that got ports to SNES. Ultima 7 Trash on SNES with a lot of missing stuff and censored story and amazing masterpiece on PC. Eye of The Beholder? Unplayable with a controller. Even Diablo 1, the most streamlined 90s PC RPG on P$1 was a shore.
As for "dream numbers for Larian", you are completely wrong. DOS 2 is always on top most purchased games on STEAM. And on Switch where Japanese games dominate, DOS2 still doing well.
