I'm ... not really sure how well that would work. The VA would have to be pretty good in order to match the character of Chris, especially in that route. From what I saw, the teasing is at an all time high, with her changing from sensual to commanding then to gentle and so on and so forth, depending on the mood.
If you know someone that you believe could do a good job and you really wish to do it, then by all means, go for it but I would recommend adding voice acting at a later date. From what I know, recording lines can take quite some time, that is if you wish to do this in a professional capacity.
