I'd echo some of the same advice as other regarding foregoing the bear hunt and focusing on the elk. What kind of break was it? Did you have any soft tissue damage with ligaments/tendons, etc of a particular grade? Been down that road as I broke my ankle and suffered several significant sprains/tears of my right ankle over the years. Every time, dedicating myself to PT after injury has gotten me right back into the mix. If you can afford it (through insurance?), find a good therapist to go to on a regular basis for a couple weeks. Not only will you benefit from it by getting healthy for the hunt, you will be glad you did later in life!
Even without going to a professional, once your doc clears you, you should start tracing the alphabet with your foot several times a day. Start doing single leg balancing and eventually single leg squats to regain control and strength. Get yourself one of these discs:

Use a ski pole, trekking pole, or large dowel to help if need be. But single foot balancing on that disc daily will strengthen those stabilizer muscles that are currently getting weak while wearing your boot.
It seems like you have the time to recover before the hunt arrives, but definitely always follow the guidance of professionals.
Also, as mentioned by others, if you don't already have them: GET TREKKING POLES. Especially to use when you are successful! Given that you will just be on the other side of an ankle injury, the poles will make a difference in getting in and out safely. I carried my first elk last year using a pair and can't imagine doing that again without them. Hope it all works out for you, heal up!
