It seems to me that with a little creativity you can have a PC (even a low-ish level PC) as a lich and still have the idea that it takes very high-level magic to accomplish it.
An example: Suppose that Mr. Evil Wizard wants to become a lich. Now, this is something that you definitely do not want to screw up. Therefore, Mr. E might want to practice. Sure, he could probably cheaply lichify his familiar or something, but we all know that reserach on animals doesn't always translate directly to humans. So Mr. E captures some poor commoner and decides to practice the spells on the captive. With the proper precautions, he can just observe that the transformation works as desired and then destroy the captive's phylactery. Easy, right?
And then something goes wrong. Right after the transformation of the captive, Mr. E's mortal nemesis (maybe a good adventuring party) crashes the party and captures/destroys/drives him away. Now you've got some poor first level lich whose life has suddenly become much more complicated.
You might not agree, but I think this sounds like a fantastic PC backstory.
