This would only work until sentient undead (Will negates, IIRC) start showing up, but it should give a few hours safety. But then you have sentient undead with the past few hours' waves of undead.

Same problem with Lichloved from BoVD. Although, honestly, maybe with that one you could kill mindless undead and they wouldn't fight back, at least as a group.

For flavour and challenge, I would recommend banning necromantic and cleric-type classes. Adds to the horror feel, I think, and limits complete bypassing of everything by turning.
I'd also have a lot of elements of hiding and tactics, instead of just waves of enemies. Do you go into the mausoleum in the middle of the graveyard to hide, but risk fighting whatever dwells within?
