I think you can build most things from just the base classes:
For a "wu jen" I'd say a wizard or sorceror... just take an elemental stylised spell selection and a careful description of the character.
I'd go one of two ways with a duelist - either a fighter/rogue, ranger/rogue or similar who uses light armour and dexterity - feel that makes a traditional swashbuckling type. Or a high Str/Dex fighter with plenty of feats in the expertise tree - more of a 1 on 1 judicial champion type.
The ones I think are really difficult with just the base classes are the multiclass type of characters. Mystic Theurge, Eldritch Knight and Arcane Trickster would be very diffiuclt without the Prcs?

The only things I would like to see is a rogue/diplomat-type without sneak attack or a nature priest without wild shape but nothing has come up yet in my campaign that have made either absolutely crucial.
I thought about adapting some of the classes from AU but there not 100% what I'm looking for.
That diplomat archetype sounds a lot like the bard... just take Perform: Inspiring Oratory and I think it pretty much clicks into place?
A cleric with Animal and Plant domains comes quite close for the second... seen that done and it worked nicely.
I really liked the look of AU and ran a shortish campaign arc with it. Lasted about 4-5 months. Found it pretty good fun. The base classes and equipment were the highlights. I liked a lot of the ideas behind the magic system, but that's where it fell down for us. It was similar to DnD but unfamiliar and just didn't click with most of my group.
I'm pretty sure the warmain and unfettered would fit right into most campaigns. Although I think players would choose 1 or other over fighters every time... they're a bit stronger and have more flavor. The Akashic, Totem warrior and Champion would all go over pretty easily as well. Just the magic users might be a bit tricky - the magister might well be worth the effort though.
The only thing I really didn't get on with in AU was the names for the classes, felt they were a little strange?
