Werebears are featured in many rpg's like Diablo 2 and tabletop rpg's like Dungeons & Dragons. They're also in Native American mythology, Norse sagas(Hrolfs saga Kraka) and novels like "The Hobbit". So why not Skyrim, Daggerfall had two lycanthropes. Plus werebears are in the lore.
Here's the part in "The Infernal City" that the main characters fight a werebear
The driver himself might have been a massive albino Nord with long, sinewy arms. He was bare to the waist and covered in blue tattoos. His mount was the largest bear Attrebus had ever seen, and four only slightly smaller bears ran along with him.
“Bears,” Lesspa sighed. It sounded as if she were happy. She shouted a few orders in her native dialect.
The white giant was gone, and in its place something between a man and a bear was fighting the Sench-tigers. It hurled two away, but even as it did, Sha’jal leapt on the driver’s back and closed his viselike jaws behind his neck. The other Khajiitwere finishing off the mount. The other bears lay in brown heaps. The werebearbawled and tried to shake free. Sul strode up almost casually and cut him from crotch to sternum."
An example by Littlewing on how werebears and werewolves can be balanced.
As for werewolves, they would be more like light armored assassins and would basically have the same health and attack they do now with the perk tree. But by adding sneak, it would complement for them for having no defence and there would be a 5x multiplier for assassinations. So as a werewolf, you could enter a fort kill most bandits by sneaking and if you're caught you could either summon spectral werewolves and use them for distraction as you creep back into the darkness or you could join the spectral werewolves and use your speed to kill the bandits.
Here's some pictures of how werebears could look like.

As for spears I'd like Iron to Daedric with Artifacts too like Hircine's http://www.uesp.net/wiki/Bloodmoon:Spear_of_the_Hunter from Bloodmoon included.
