If you are close to a good outdoor store, you could compare yours to a level or two better, supported like UH suggests and see, make sure to look for detail at distance. Many stores will let you go outside to look at distance. Bet they would let you take a large display tripod outside too to use. I suspect the best answer for you to your query will become clear.
I'm not familiar with the optical quality of your diamondbacks, others may be. If you upgraded the bino's, what is the budget? Are you doing only 1-2 elk hunts ever and guided or diy, public or private access? Those answers could help decide about a bino upgrade. If you don't own a tripod, eventually you'll probably want one, so a tripod purchase would not be "wasted" in my mind. For me, very good glass is enough, 95%+ of the big three for 1/2 - 1/3 the cost. My guess is for 1-2 hunts out west your diamondbacks will work well, will work much better off a tripod and better glass off a tripod would be even better...
