Have it done the way you want it mounted, and then leave it at the taxidermy shop until you get her to kill one. After that, there won't be any problems.
Since my wife's first animal mount, it's been no holds barred. I always give her the option of hunting with rifle or bow. She mostly picks rifle due to her comfort level(she has wrist problems and a lot of flinging arrows is painful). Her mount count will soon overtake mine! She has taken 3 bears, 4 bucks, 1 moose, and a caribou.
I better start flinging arrows!
