Grey Knight Masters of the Chapter

One of my (2007) Christmas presents was a box of Space Marine Masters of the Chapte.

…and here they are out of the box in their raw metal state.

It is my intention to paint them up as Grey Knights. I am attempting to paint a Grey Knights force which goes beyond the listings in the DaemonHunters Codex. What I am trying to do is to create a Grey Knights force (using the Space Marine Codex) and then using a DaemonHunters force as allies.
