A full mount form would have to have the back legs area cut off and the back belly cut at the angle you are looking for. I've never seen a half or 3/4 mount for a running or charging boar that is tighter to the wall. In fact I'd be hard pressed to find any half mount hog form in a running/charging pose. Pretty much something to discuss with the taxidermist in person. This is a custom mount all the way! A good artistic taxidermist can do drawings or make a clay model to present to you for your approval, then go from there to form alterations.
