I like the idea too and the levels max difference too although it would be cool to be able to help the new guys in other way than send them cash...

I say go with average stats. it is how it works in real life too. If 3 geniuses plans a crime and then take a real dummy to help them, something will go wrong somewhere for sure. Will they have enough intelligence and quick reaction to fix it or cover for it? That's where the average stats would do it.

I think the coding (although I'm not an expert either) would be somehow similar to the 1 for gang crime, less the activity side since both of them (or more if we could do 3 or more people crimes) need to be online at that moment to do it.

And yes, split everything, even the jail time with a ratio on level.
