Can ghost sims be converted to Vampire?

Have a sim get bit. They get the debuff saying they will turn in a few days I think it is. (It might only be hours, I don't quite remember how long it lasts). Kill that sim while the buff is active. They should still turn vampire after becoming at ghost. It happened to me purely on accident but it works. ;) The vampire can't bite the sim as a ghost because ghosts don't have plasma. Of course you can also just kill a vampire to get the ghost but if you're looking to see the ghost animation turn vampire, the only way to do it without a mod would be to have the sim die after being bitten.
