Night Lords souping in a Knight Abominant?

[Kaldoth]

So, with the Arks of Omen Detachments being a thing now it no longer costs 3 cp to bring in a knight for a healthy bowl of Chaos soup. It got me thinking about that age old question of "how do I hit that sweet -4 LD debuff." While we unfortunately still can't get the house Korvax ability in an Auxilary Superheavy Detachment (sans Be'lakor shenanigans), what you can get is a Knight Abominant.  Each psychic phase you get a point and click 18" -1LD debuff on a 5+.  And of course, all of the other benefits of having a Knight Abominant to throw up the field.  Well, now that Knights don't cost any CP to take has anyone thought of souping one in? I personally refuse to play daemons, but that is purely because I refuse to paint them

CSM lack firepower, you want a knight that has AT and mass damage potential.
