Double Creek, your post seemed aweful intelligent. And I have no idea what your point (if there was one) is.
Trun the 3-d target on a 45 degree going away, coming toward. This is the beauty of a 3-d. Set it up a million ways and shoot all of them. Sometimes I like to set it up in a shooting lane and try to thread the needle. I practice shots on my 3-d that I'd never take on a deer and this give me the experience and confidence to drive home the shots I do take.
Sure you can do this. And I'm sure it is great practice for someone that already knows where the kill zones are from different angles. But how does that help somebody LEARN where the kill zone actually are, or where to aim, such as the original topic suggests. I have seen 3-d targets with the kill zone drawn in, but only at broadside. Never from an elevation, or quartered away. That was my point.
That is why I recommended the book that I did. It shows all North American Animals in many different positions including elevated stands. It also shows the vitals drawn in as well as aiming points for archery as well as gun.
There are some pictures listed on here and other places, but they are very limited in angles.
Another great source of information is here:

The poster show an actual deer that disected in order to see the exact anatomy. There are also posters that show actual blood types (deer, from different hits) as well as hair types.
