I believe that such a thing has been discussed by players (myself included) on some older thread, and a consensus was that it appeared to be possible (I could have misremembered, but these were the details iirc).

Vanila Bow mechanics already account for drop and slight change in position, it might not be too hard to assign a random decimal to "accuracy" and then add that to the trajectory of the arrow. Higher alignment (or other stat) would mean a smaller variation in the trajectory, likewise, a lower stat would mean a greater variation.
