I think it would be cool if Ikuto continued identifying as a guy instead of conforming to the new body, and it was already stablished he isn't against a gay relationship, and Liam's family is open too, Liam wasn't ready to accept it but he recognized his feelings for Ikuto before he knew Ikuto was "Isabella". It would be cool having a trans guy protagonist even if it's that his past life was as a cis guy.
