The first set of wheels I ever built, newbie, no instructions, I accidentally had the spokes crossing above the valve hole (rather than "correct" parallel), no problem, plenty of space for the pump head, but that also meant 180 degrees across the rim at the joint, same thing. These welded steel rims, not an issue, but the same thing might work, but I don't know how much force it will pull them together with, you could trig it out assuming a given spoke tension.

All the spokes crossing, you would think would have a tendency to pull everything together, but I think it all cancels out. Except perhaps local to the joint like I noted above, and even that I am questioning in my mind, I'd need to draw it out.

For the joint to come apart, the rim needs to grow in circumference, and all the spokes are fighting that.
