Is this game being made first and foremost for those who hold BG1 & 2 as the apex of computer RPGs? If not, there is no reason to be so beholden to the original (in whatever way the aforementioned group thinks that should or even can be achieved).
Do you care about the name of this new game ?
I was going to include something on this, but I figured I would wait for it to be asked (as I knew it would). So, to answer, no really I don't care. I know it does to the BG1 &2 devotees. But again, unless this game is being made first and foremost for that group, the doesn't matter. "Baldur's Gate" means nothing to newer gamers, and it doesn't mean to plenty of others (if not a massive majority of others) what it means to the niche group that holds the game so high.
