Suggestions for a Crusading force?

[Merkava]

So after pulling out my Ultramarines 2nd company that I painted 5 years ago, and after shuddering (five years of learned poainting skill + washes = better looking curent models) I've decided that I'm going to try stripping them and starting over.

 

Now instead of just redoing the 2nd again with my new painting process I'm using for UMs, I'm thinking this is a perfect oppurtunity for a change from blue and do some other colours. I'll be doing a crusadeing force made up of sicarius and his command squad and the first squad as UM's. This keeps it so I can use sicarius as the captian still. so that leaves 9 more squads. Any suggestions? I'd like to keep the squad as something that it's parent chapter would be good at ie. strong devastators. And maybe all UM succesor chapters but that isn't set in stone.
