Thorns + bucc with no stun mastery = bossing bucc?

Does anyone see this as a viable build? The 20 points in stun mastery could go towards lolwave, and if you have a thorns mule training and bossing becomes much easier.

No.

Getting a character to level 130ish just so you can add 20 points into a skill you won't even use often doesn't seem like a good idea.
