I'd recommend 3d printing some TPU spacers where you see the threads visible. This will a) protect the threads b)give you something to compress against, otherwise those bolts might work themselves loose. Over time, you will tighten them which will eventually deform the bolts. Looks great.
Unlikely, as I only own x2 BEGODE wheels. These are designed for the master and are custom too, they require a slot cut in the pole. They have been made to accommodate 100mm suspension travel and extra clearance from the tyre on bottom out.
