Thought I should add this reference to an old thread which discusses 36->24 lacing: 36/24 spoking...again

I had already figured out that the 5 degree offset between flanges lead to that you will need two spoke lengths. That's not an issue. I wonder though if there will be some torque-issue or similar thing I haven't figured out...

There's also a solution when using a standard 2-cross (equal spoke length) on one side, and radial on the other, here: https://www.sheldonbrown.com/rinard/36-24.htm actually the radial side needs two different lengths, but as they differ only about 0.5mm it's generally negligible. I would prefer 2-cross on both sides though in this build.
