Starting a day early might be a good option -- if you can get the permit.
I believe you could find a place to put down your bed at most of those first (Panther Creek) crossings, even if you have to use a wide spot in the trail. Doing that would put Hamilton lakes more within reach the next day.
If the early permit is not an option, the stealth would be my next choice. Be sure and find out, I think the wilderness ranger desk at Lodgepole closes about 3 PM, so you need to get there in time.
