Actually, there were plans to include that indeed (Japanese dub)
Since the voice of Alisa is done by a native Japanese person. (my girlfriend XD)
So the main characters in the game would stay the same actor/actress.
That's awesome man! I hope it comes but definitely no issue if it can't be done. I'm super excited to hear some more from Pol, the voice acting from him is excellent and hilarious too. There's a lot of fun to be had in Alisa and I can't wait for that September release :)
