Don't think they should re-record the VAs. Not that I think they're perfect (though for the most part, they are very good), but that it'd be very easy to sour a lot of people on the remake if they're different. Better spending their time changing guard patterns or improving the interface (say, being able to swap camo in MGS3 without going through those menus) if they're desperate to do something more substantial than making them look cleaner.
