We're pretty close already (and I, who hate most western voice acting would argue we're already there) to the AI being able to use the input from the Japanese Seiyu and the text of the new English line to do a better job.
Most ethical issues evaporate, and I believe many people would find it preferable, if some of the money that would have been used to hire English voice actors instead went to the original Japanese cast in exchange for the use of their voice's likeness.
The Japanese industry is very different, and they just do a better job and avoid the ego trips so common on this side of the Pacific.
