I have a third dreadnought which I may strip and repaint as an Ultramarine (It's currently got Mentor colors, but I don't use my old minis for my Mentor army) but I've only got the close combat arms and I don't see a good choice for fielding a dreadnought with that weapon configuration. It also has literally two right feet. The left foot is actually a right foot surgically modified to fit, and it's not very slick at all. I stole the missile launcher from it and repainted it for Hamus.
