Tree-climbing gear for my gravel bike?

That Road Link is a Wolf Tooth product? Keeping the 31-48 crank ans just being able to go down to 42 sounds ideal. What's the cassette? SRAM? Shimano?

Both SRAM and Shimano make 11-42 11-spd cassettes for mountain bike applications. You will need to adjust the spacer on your freehub to fit the MTB cassette on a road freehub properly. Something like the Shimano SLX CS-M7000 should shift nicely and doesn't cost an arm and a leg in case the experiment doesn't work out.

At $72 that works for me to experiment with. I've seen some of those MTB dinner plate cassettes at some insane prices.

Something like this might work well...they offer chainrings in 2 teeth increments so you can customize. More expensive up front, but might be a better solution for lower gearing than going bigger cassette jumps.

I have a WI VBC crankset on my main all-road bike. I used to run 48/30 (with a 12-30 cassette), and before my 11-days trip to the Alps this summer I switched to 46/28 (with 11-36 cassette). It's basically a 1-by-with-granny setup. Most of the times I'm in the "big" ring. I have DT shifters, and the shifting performance between the rings is fine. For the shift to the smaller chainring you have to ease up quite a bit; the other direction is very smooth.

I'm really glad I had gears as low as I did. On an 11-day trip with some luggage, it's super helpful to be able to spin up many mountains passes in zone 2.

What 11 speed 11-36 cassettes are people using?

I don't think Shimano makes one, do they?

As noted I'd start with an 11 speed 11-40 or 11-42 cassette and see if you can make it work. You'll almost certainly need a longer chain and increase B-Screw tension but it might work okay WITHOUT using a road link. My understanding is that the road link will help if you can't get the derailleur to shift onto the 40 or 42 even with the B-screw all the way in but you'll still have the same chain capacity concerns (likely slack chain in the small/small).
