Horus Heresy. Mechanicum magos dominus. Next project

So i got this bad boy. Can’t wait to paint him up. I was thinking of using him as a magos dominus for my mechanicum army or what will someday become my mechanicum army. After I ordered him I started to think about how to equip him. I guess that is a noob mistake because I realized that I want him on a abeyant. So I should have bout the real deal from forge world to begin with. But I really like the look of this guy. So for now I will probably just convert one up. In the future I will need more HQs any way so I will get the official model at a later time. Just need to get my current ork project out of the way before I can start putting this one together. Praise the omnissiah!
