Just have to make it through bleak falls at least. Will you be using a follower, I think you may need one. Big struggle early on bit like a pure mage but may be ok once you get a few decent shouts under your belt. Would be interested to know how you get on if you stick with it. So many Fire Wyrms and dragons breathing fire Will certainly be a challenging build that's for sure. I have done it, and its seriously over powered if you use the restoration loop to give you 0 cool down. I just have to keep the amulet on otherwise the effect wears off. I plan on making use of a restoration potion to make my amulet of talos give me very short Cool-down. Basically the character only used shouts or his fists. I've done this, it's pretty hard though with the cooldown.
If i get bored i may try to do unarmed, but that would require me to either go into enchanting or heavy armor. If i stay a low enough level i might be able to damage foes pretty well. Bassically I will get a pretty good restoration potion to shorten the cool-downs by a pretty good amount.
