I couldn't see Mark working with Shaina, Mark is more old style country, Shania is to modern and polished for him, I like Shania fine, but I'm doubting Mark would produce an album for her, but stranger things have happened, then again, when would he find the time to do it? Well with his solo album due to be completed not long after xmas, and the release not till September, maybe it could be a summer project!!
