The Kurain technique and the Fey family could certainly be a thing that exists in the setting, sure! There are, as you say, quite a few Trainer classes based around the concept. We will not be introducing a Spirit Medium profession since that's a little more specific and esoteric, but the professions do not cover the full range of everything to be found in Union, no. I'm not sure if you're asking for her to be a real spirit medium, but if you want that, let us know, and we'll discuss that matter further.

As for Shifters, actually, both Shuppet and Pichu are found in the wild in a few games. Our stance on Shifters will generally be that they will need to start from the first evolution, including pre-evolutions. We will give consideration, though, to species that change dramatically upon evolution in appearance and type. Also, if there are any extenuating circumstances you feel should qualify you to start at a higher level, you can contact us and we can discuss that on a case by case basis.
