I agree about making the mod that makes it possible to tell the gender difference among kids incorporated as base, just for the sake of variety.
Oh, and about that digging graves for party members who die in combat feature:
How about this, if a party member dies in combat and the bad guys are all dead, than you could have the dialog option of saying things like, if for example Myron died:
"Oh god, not Myron!! He may have been an irritating brat at times, but he didn't half to die like this. The least we can do is give him a proper burial".
He gets buried and, with every other party member saying some last words for the fallen party member, like Marcus(The bastards who did this will pay), Sulik(De spirits will guide this soul to the valley of chosen souls), and so forth. Dead party members grave site will be marked as "Marcus's Grave" on the map, and maybe random bystanders will stop by the grave site and leave money or something.
Or, if your an evil character, you can be more dastardly. You could just say something along the lines of "What a useless fat bastard Vic was. Well, him being gone was just one less piece of useless dead weight that these god-damn wastes are full of. Let's move out gang!"
Or maybe, if you have a good enough skill with melee weapons, you could cut up the dead corpse and sell it to any random brahmin dealer/slaughter house and the can give you money for your recently aquired meat. I mean, this is a world in which anarchy is prevalent, so why not add in anarchic things in, like selling people meat? It could even be a negative karma title, "human butcher". This tag could give you a melee weapons boost, and a negative karma modifier that makes some people not talk to you since your such an evil looking guy, do to you butchering people all day.
