... Continue your PT, keep the rest of your body in shape, and see how the ankle performs as you eventually move back into a hiking boot and hit the trail again (not "hit" as in last time though - please).

Your hike is set up nicely for your situation: 4 miles with a heavy pack the first day and 2 miles the second day. That second day 2-mile hike will be done very quickly, so spend a lot of that day acclimating at TC and resting. Have some marmot stew for dinner. The 10 miles on day 3 will be the longest, but your pack will be much lighter. You may find the last day the toughest - hiking 6 miles downhill with a heavy pack and a potentially protesting ankle. Presumably you'll be using trekking poles? There's only one correct answer to that question.
Bulldog, you cracked me up several times: the marmot stew is a great suggestion! Yes, I have gone back to ultra clean living to heal and it is paying off: eat lots of fresh sauteed veggies, high quality protein, drink 2 liters of water per day on top of other decaffeinated beverages, atkins bars for those sweet cravings to avoid sugar, and I am always crutching around for exercise which gets the old heart pumping. I am telecommuting for work now so the brain is not atrophying on TV shows. As for those hiking boots, I am wearing the same one on my left foot that the ankle was broken in because it is the only shoe thick enough to match the frankenstein boot to keep my knees even. And yes, I am a firm believer in hiking poles. The SAR team was struggling up the steep trail to get to me and called back our cell phone to ask if I could move at all so they could get me out before dark (this happened on the day before the clocks changed to daylight savings). That set of 10 yr old Leki poles was the reason I made it about 3/4 of a mile on a broken ankle (while grabbing my husband's shoulder of course to do a 3-legged race kind of hop) to meet the astonished SAR team who splinted me, threw me in a stokes basket, and got me out to my eternal gratefulness. If not for the cell phone working I would have had to go out all the way out on the poles. And Yup, I had a headlamp too just because you never know!
Thanks for the food for thought about the last day. Downhill with a pack is more stress than normal so both my ankle and quads will have to be in shape. My husband and hiking buddy love me, but I doubt they will 'willingly' take all my gear back to the portal. If they do, it's gonna cost me in a 'remember when we' story I will have to live down for the next 40 or 50 years at the most awkward times lol!
