I would say drop the mega nobz

but since they seem to be the reason why you posted the list in the first place I know you not going to follow it. Second I would not mix BW with kans

since you don't want to hear that I will ignore it. So I am left with criticizing the rest of your list. Drop the KMB on the kans and swap them for rokkits, I know AP2 sounds tempting but the difference is terminators saving on a 3++/4++ most of the times rather than 2+ and being useless on the rest. with 9 kans and 2BW you definitely need another
KFF. The dread is not bad but I would think in swap their
BS with skorchas or drop him entirely
