I say euro, but whichever way you go include some additional elements such as stone, or a log, a little snow, and certainly some sage on this case. The brass from shot? Elements of the story. Then, and perhaps most importantly, three or four nicely framed pictures to hang around it. Have the pic of the two of you a little bigger. The picture of the two of you will ultimately be more important than the mount.
Really comes down to whether she wants a full mount in the house.
edit: found this pic on a quick google search. Change aspen to sage, perhaps add a little snow, choose wall mount vs. table, etc. Just an idea.
