Do you suppose your sim could become the 'fourth' sage, of Alchemy?

Maybe deleting them would just spawn another one, because they’re important to casters. Just like Vlad, if you cure or kill him, he is replaced with another high ranking vampire. And since the sages live on a hidden/non-residential lot, you can’t just kick them out and pretend that your sims are sages that way either (like how you could do that with Vlad).
