I still want to be able to do something with tombstones other than just look at them
-Decorate my house
-Send food to the Dear Departed in Hell
-Kill gnomes
-Crush into elements
-Use as the foundation of new streets
-Stack up to use as ladders
-Throw into peat bogs to be found by future archaeologists and glitchopologists
-Summon the spirits of the dead to stun the Rook
Quite a few religions allow for prayer and/or donation to ease the suffering of the dead. Perhaps donations of food or drink at a gravesite could make re-life a little easier (via mood and energy boosts) for the temporarily-departed.
