BLF Kronos X6/X5 GB - Group Buy now closed.

Is here anyone who is invited into manufactoring process?
Does head`s internal thread end synchronised with holes position?
I`m thinking about X5 quad pill/spacer and interested if it is real to make such pill, screw it into the host, mark holes location from driver`s side and mill grooves for wires to except host drilling. If each host has difference in thread end and wire holes relative positioning, spacer without thread is better way.
