All the Stopwatch final items provide armor, wouldn't it make sense if Stopwatch provided armor too?

Guardian Angel: +30 armor Zhonya's Hourglass: +45 armor Gargoyle's Stoneplate: +40 armor All building out of a Stopwatch.

Balance-wise, having a Commencing Stopwatch at the begining of the game providing some bonus armor might be too strong. But it would make more sense.

I can totally imagine the Seeker's Armguard building out of a Stopwatch and an amplifying tome, keeping both the Stopwatch one use active(if not used before) and the passive stacking, aswell as the introduction of new items for the building of the AD and Tank counterparts.

#(This is pure speculation, not an actual suggestion.)
