Primaris reinforcements?

I recently got myself a copy of Dark Imperium.  Mostly because I wanted the awesome new Primaris marines that come with it.  I've already begun assembling them, starting with the characters.

I haven't decided yet whether I will add them to the chapter or start a different chapter.  I have always wanted to do a Blood Angel army...

So for now I'll just focus on assembling them while I paint my Custodes instead.
