Hot take: both the father AND the son should've genderbent. I like the fact the author is trying to restore the bond between father & son, but it risks having oedipus complex vibes (cringe). Likewise, if the son got genderbent, it would have electra complex vibes (also cringe).
The only solution is to genderbend the both of them, and have wholesome mother-daughter bonding. Also, they should have the "Yamato Nadeshiko" phenotype, rather than the semi-gyaru appearance Mrs. Dad currently has.
That's just my 2 cents though 👉👈
