Game ends on party death

Me and my 2 friends are playing heavily tweaked, SCS included BG2. The difficulty is significant, so it happens that our protagonist bites the dust. This is getting increasingly frustrating, since more than often we have means to win the rest of the fight and ressurect him thereafter. Instead we need to go for immersion breaking reload.

Therefor I am looking for a mod, which would trigger game over on party death, instead of just protagonist death (just as in Black Pits 2). It would be also cool, if the mod is compatability friendly. Any hints?
