Sorry if I'm expressing myself poorly, but English isn't my first language. I know it would be a form of turn-based combat, but what I'm talking about would require a systems, encounter and level design overhaul, as turning those options in the game in it's current form, does transform it into to much of a slog. It would require, at least the removal of the most pointless encounters, and wouldn't be something as simple as tweaking the options (although, in some areas, that helps).
Anyway, I'm not detracting anything from the Baldur's Gate games, and I still enjoy them for what they do well in the narrative and roll-play potential. For me, (emphasis on "for me") the combat isn't the most well realized aspect, as it lacks the clearness and user-friendliness its complexity requires. "Fixing" that, would unbalance the rhythm of play in a major way.
In the end of the day, to each his own. As for me, when I find myself revisiting Baldur's Gate, my CTRL an Y keys might see some unusual usage.
