Great Effort!
I’m doing a similar style of trip, mainly hiking/transalpine but carrying a packraft to get across rivers that would be otherwise uncrossable. I took a couple of paddle blades from a cheap beach toy inflatable and drilled a couple of holes so I could lash them to my walking poles. Good enough to cross even a quite fast flowing river, although I’d want something better for descending such a river. (Yes, it’s a Klymit LWD, I’m in the early stages of building a Skeena, but would really like to have a DIY Ultralight for such trips where I’m carrying ice axe, crampons, small alpine tent and a packraft).
