It would totally work. You could go up the right side and get daedric and dragon smithing in case you get sick of nightengale. You could not use enchanting to fortify smithing to keep your dagger damage reasonable and your bow damage for that matter. The archery perks are nice, especially quick shot, so you won't need a bunch of damage anyway, and the ranger perk would give you mobility in stealth in conjuction with shadow warrior too, so you can keep moving while sneak attacking.
The downside is nightengale is a leveled item and I personally think sneak attacking with a bow all day is tedious. You also won't get glass smithing perk, unless you want the whole smithing tree, as deadric is near impossible to find. In later levels you will be fine, in the early levels if you can't get in backstab range you could always drink an invisiblity potion. You'll also have shouts like Ice Form in case you aggro everything, to buy you time to re-enter stealth. I took illusion for calm, muffle, and invsibility, so I've been spoiled by that.
