I'm not going to lay this out, but my general guideline is that I don't want spokes more than 1-1/2 or 2" from the hub's center. That's roughly comparable to building 36h 4x on a classic large flange hub. So very large flanges usually call for fewer crosses.
The reason is that when spokes are too far from radial, the spoke/nipple alignment at the rim will be problematic. On very tight wheels, spoke twist with misalignment bends the spoke back and forth at the nipple and leads to breakage at the 1st thread.
On any given rim, you can thread a single spoke and nipple, which will naturally take a radial line, then bend it off radial and see how much movement the spoke hole will accommodate. Use that as your working guideline.
