Umm, yes? The Icewind Dale mod is at a demo release stage currently, only the Prologue chapter is complete so far. The mod can be found here. Keep on the Borderlands has been in a full Beta release stage for a while, not all party alignments are supported, and the Orc Caves at the Caves of Chaos are unpopulated, but the main bulk of the game is both very playable and enjoyable, it can be found here.
I did originally plan to do just that, however Baldurs Gate would be a far bigger project, and at this time ToEE's engine isn't able to handle the vast quantity of maps that are needed to complete the project. The posibility of expanding the number of possible maps in ToEE is being explored, and while it would seem to be possible, the currently hardcoded limit of available map numbers has not been raised yet.
