Sorry I did not mean to imply sarcasm. I wish the best for people undertaking the endeavor. Wouldn't want people stomping all over my Chrono Trigger movie script before they read it, so I'm not really into criticizing people trying to make a project happen.
I personally never pictured any of the characters as having an accent (outside of Japanese), and while some of the translations in the English dub of AC make me want to throw something at my TV, I really didn't have much of a problem with the voice actors' performance.
One thing I might point out though is if the intention is to get a "unique" character presence by using an accent that is regionalized in some way, then it would be contrary to that goal for half the cast to have that particular feel. Unless the uniqueness is to come from the few that are an American/non-regionalized accent?
