Anyone thinking of dumping their (or a) faction to get into Convergence?

I have 4 factions for WM/H. 3 hordes and one warmachine. I don't like going over 4 because I have too much to paint as it is. One of my factions (Trolls) hasn't been touched since last year. So I'm hemming and hawing about dumping the faction and getting CoC as a 2nd WM faction. seems like an interesting challenge to paint. Anyone else going having the same thoughts about switching?
