I'd probably do it if the antlers were big enough. I'd just take the antlers though, not have the head mounted.

I have many sets from deer I haven't killed. Some were given to me when I was a kid, a couple skulls I found, I bought one full skull off ebay for about $5 just to have because it was so big and only five bucks. The only one I have on the wall as a trophy is the second deer I shot.
