Deuce Traveler
Adventurer
This could work if done right, and is an intriguing idea. I'd have the player be on board for it, though, as it can end in an epic manner.
There was a 3.5 third party manual of some sorts that allowed for a party of liches. In this alternate rule set, liches were actually somewhat common and actually had their own city they ruled. As the lich leveled, however, he had to take up a mental flaw. So the PCs were powerful, but as they developed they would inevitably gather a host of mental disadvantages which would guarentee self-destruction at higher levels due to their increased insanity. I actually thought it would make for a dark, brief, and yet fun campaign.
