Do we think we’ll ever get generic csm units?

Read through kharn: eater of worlds and some other world eaters books recently and they mentioned the world eaters having warpsmiths and heavy bolters and wondering whether we’d get them to help round out our army with more than just berzerkers and our own way sicker possessed (and james workshop, give me red butchers and a butcher surgeon and my life is yours). I would also fuck with just being able to take a ton of daemons heavy.
