Road Wheels & Road Wheel Recommendations?

Which reminds me, I need to swap the hub in my Time Machine rear wheel from a 10 speed to an 11 speed.

Is this something I could do without totally FUBARing the wheel, then take it in to be tensioned?

Just detension the spokes say 5 turns each moving around the wheel till the hub and spokes fall out.

Last time I did a rim swap. I did it step wise. So that at one point both rims were laced to the same hub. Could'nt be arsed rethinking the lacing. Not sure you can do that with the hubs.

I still need to move 4 spokes on my crabons. But I cant face regluing.
