I'm curious to see if anyone else mods the permanent CON loss penalty into the Raise Dead/Resurrection/Harper's Call spell to bring it closer to the 2e PnP version. I've found that it significantly changes the way I play the game, since it adds a more believable, finite component to bringing characters back from the dead (as far as playing a fantasy RPG goes). It makes character death mean something other than spending gold and possibly missing out on some XP.
It was pretty easy to mod the CON loss in original BG, since the engine subtracted any bonus HP given by a high CON score from characters' maximum HP total. The BG2 engine unfortunately reversed this process, so if a character goes from a 15 to 14 CON, any bonus HP are subtracted from her single, current HP upon being raised, which results in her death once again. How annoying!
Since the EE versions are based on the BG2 engine, I decided to make Raise Dead identical to Resurrection, which fully heals the character upon being raised, but with the loss of a CON point. It's not PnP, but it's much closer than the way the spell is currently implemented in the game.
I remember "MyNameIsNotLily" had a Let's Play BG series years ago, and he had the CON loss installed. I think Jaheira had something like an 8 CON later in the game from being raised so many times ^.^
