Adding to a harem with just normal monsters to live forever probably wouldn't work because there is a limit to a harem's size. When reaching said limit, even a bicorn's abilities won't be enough to attract other monsters to the harem.

On the other hand, including a undead monster in the harem would probably work (incubi married to undead gain necessary undead traits even without dying), if for no other reason than that the rest of the harem will have easy access to a potential means of becoming undead themselves.
