You can adopt a child, technically.

You can... If you find a child who is foolish enough to agree to live with you in an ice cave )))

Or study Ishnadan magic, but that's an option for extremists.

Adopt Meligor.

Personally, immortality seems much more appealing to me than the ability to have children.

Well... Not for me. Besides, immortality is a relative thing; everyone will die anyway Revan will kill everyone
