Phaethon and the Heliades. Will there be 6 more "students" from Helios with implants?

In Greek mythology, Heliades are the seven daughters of Helios. After thier brother, Phaethon, was stuck down by Zeus (who must likely be the creator) they end up turning into tree crying tears of amber.

Seed herself seems to had taken some inspiration from this. Its not one to one, after all she associated with flowers instead of trees. And her crying was for a different family member.

Similar to the Wise and Bell, Seed was given implants allowing her to control machinery.

Long short of it, do you think the writers would try to add 6 more characters from the Academy? And if so, would each one having control over something associated with the elements from the game?
