We have another round of unclear players in the queue.
Regarding immunities, I would leave them as they are. We definitely don't need more immunities, and fewer... well, we could probably remove them from those who missed their turn, although I'm fine with the current setup.
Sharing my experience: in our games, the GM gives tasks to solve. The first one to solve it (or not necessarily the first) gets a bonus, such as immunity for the night or the day. Not for the _first_ night, but for the night/day _following_ the task's solution. But honestly, I doubt this would work well in HvH.
Regarding the necromancer. It's pointless to forbid the moderator from speaking and hope that he won't circumvent this ban. It's easier to introduce restrictions on resurrection, exactly the same as for replacements. That is, you can "resurrect" (in quotes because I remember - resurrection without voice and no new information, just for chatting) a player who, according to their role, does not receive additional information. That is, all kinds of blockers, shooters, healers... Moderators and mountain dwellers are out. You can also resurrect mafia members, why not? It's just for fun. Although if there are two mafia members in the game, you need to think carefully before allowing this.
