Using Sundren custom content in Single Player modules?

[Baculus]

(Long story short, *topic*)
I recently came back to Sundren and have been amazed by the new amount of classes and feats. So far during level ups(on the server) the open classes do not appear, which isn't a problem since I have no intention of multiclassing.

But I'd like to give some of these a shot in the official campaign(The Dreadmaster, combat medic, and Samurai both seem like a perfect fit for a story) yet have no idea how to enable them(And google yields no answers)

So I was wondering how(Assuming it's possible) to enable these custom classes and feats. Any help would be appreciated.

Not going to happen without modifying the original campaign which I don't recommend, also most of the content isn't available from what we give client side, and is managed by us only (like the spells and code for the feats)... which you won't get from us.

That's a shame to hear, though thank you for the prompt reply.
