I may look into both Loot and Immersions and NPC Overhaul to see if they work with GenoHaradan Legacy but if one of them don't I will look into it to see if I can release a patch. If they both work then my mod isn't what's causing your crash.
As I'm not up to recruiting Voice Actors, I cannot answer that at this point.
I don't think it's the NPC Overhaul and Loot and Immersions mods causing the problem. I installed them together with restored content mod without your mod and got no crash. I think you need to release a patch to make it compatible with Restored Content Mod.
