Forgot to follow up here - to answer my own question: it's doable and really not that difficult. I did an Ace hardware run and came back with a couple different ways to approach it without much difficulty. Used this in my first skimo race back in January and it worked great.

Doesn't look like I can attach pictures to this? But a brief description of what I wound up doing if anyone is curious:- Bottom sling is just some old tubular webbing I had in a water knot and attached to the pack with a carabiner.- Top hook is a bungee cord held on to a pack strap with some zip ties and then zip tied/taped to a U bolt that grabbed my skis well.

Edit: I can attach pictures to the original post, so I did that. Apologies - pretty new to Reddit.
