Shai strikes me as more of a ranger than a druid anyway, to be honest. He hardly ever casts spells. He's much more martially oriented.
A beastmaster ranger...maybe with a barbarian MC or something...could be quite nice.
Looking around, a beastmaster ranger with a druid multiclass would allow Shai to both keep Dyspeer AND his wild shape ability. jkason worked pretty hard incorporating that first wild shape into the game; he's not going to want to give that up.
Hmmm...there is a dire wolf mount in CB...you might need to bump it up a bit though as it's a level 5 creature, also they're handled differently as you and the mount can't attack in the same turn.
I'd also suggest looking at the ranger build with the animal companion.
I was bored at work right now so I put together a proposed build for Caerwyn (using the hybrid rules though). Reason I did it is that he had rages in the initial build and seemed like a fairly important part of the character that I didn't want to lose. The paragon class Gray Guard seems to fit his personality perfectly, "Your tactics don't make you popular with others in your god's service" & "the ends justify the means" - like his initial "concepts of quick and dirty justice" from his background section.
That looks pretty good, actually. I glanced at the hybrid rules, and they don't seem all that complicated I guess. Especially since they're in the CB now to keep 'em legal. I'm going to be in a bad way when my ddi subscription runs out in march!
