Playbooks

Any thought to new playbooks for Regiment?

I like the idea of the Military Journalist, as from Full Metal Jacket, but that's only because that's what's on my mind right now. 

Combat Engineers would be cool and useful, Chaplains would be really good for certain settings. 

That said I'm providing notions without specifics, but I'm curious, too, if there are thoughts "against" having more playbooks, would that dilute the experience?

Tank crew and engineers have been on my list. There's a guy on the story games forum has done work on the war journalist.
