Khorne Add-Ons

I have an Age of Sigmar box coming in the next couple of days.  My wife has told me that if I paint up the Stormcast Eternals that she'll learn to play.  That means I'll probably end up playing the Khorne side of things.  I really like the models, but I'll eventually need to add on to the army.  I went through GW's website and decided that the following units will fit in well.  I'm trying to avoid any of the older aesthetic models.  I'm pretty confident that the below units will not go out of date anytime soon.
