You do realize that there is no anime past the Fullbringer Arc... right?

Some story possibility here.

Have Ichigo using their mother's last name, Branwen, and you could switch him in for Blake and still have it be RWBY.

Having people around him viewing Ichigo the same way they view Pyrrha.

Then add him in the middle of Ruby meeting Weiss and watch the sparks, responding to Weiss's outrage with vague indifference. Then Weiss realizes that Ichigo is one of the two undefeatable students at the school and see her break apart trying to salvage the situation.

With them being twins and Ichigo's signature attack and fullbringer looking like black fire, him and Yang could be referred to as the Black and Golden Suns.
