What would happen if:

Anck-su-namun reincarnated as a boy and Imhotep as a girl?

Anck-su-namun reincarnated as a snail and Imhotep as a lemon?

Anck-su-namun reincarnated as an 80-year-old lady and Imhotep as a 2-year- old?

Anck-su-namun reincarnated as an elephant and Imhotep as a cricket?

Both of then reincarnated as either both boys or both girls?

Either of them reincarnated as one of Evy and Rick's next children?
