So in reading through Keeping the Peace, I noticed a few things... The Armorer Tree, possibly with the Move power, makes for a great instance of the Jensaarai, supposing you eventually get cortosis armor. The Warden Tree is a pretty obvious nod to the Wardens of the Sky, from SAGA Edition. And lastly, Warleader, with some ranks in Dodge to simulate reflecting blaster fire with your own blaster fire, will do a great job of handling the Gray Paladins.
Now in the Core Rulebook, none of the talent trees that weren't Lightsaber trees really jumped out at me as being a particular Force tradition; just variations on that style of Jedi. Keeping the Peace definitely feels like FFG is embracing the more esoteric traditions, so I ask you, what careers do you think will get a tree for what tradition? Not exactly that tradition, but at least a tree that will be pretty close, mind you.
