I couldn't remember for sure so I started up my game to make sure what I say is a yes or no.
If you try to create a spell caster they will not have the option to have the pointy ears, there are mods though that do have pointy ear sliders. I do have one work around if you want the pointy ears, start out with creating a vampire (you don't have to bother with the dark form). After you have completed the sim, take them into live play and use cheats or the MCCC mod can also turn them into a human. From there you can in game play turn the sim into a spellcaster. I have done this in the past, and was able to keep what I had put on the sim.
Someone else might have suggestion on an easier way of doing this.
