Why wouldn't that be a valid analogy? If two arrows spend the same amount of time in a crosswind starting from a static position, the heavier one will get moved a lesser amount (from the crosswind) due to the greater inertia of the arrow. That assumes same shaft diameter and fletching style.

You could easily prove this by dropping two arrows of the same shaft diamter, but with different weights from a tower of some sort. Since they will fall at the same rate due to gravity, the lighter one will be carried farther with the crosswind.

Of course when looking at this situation from a shooting from a bow with these two arrows- to have them spend the same amount of time in the crosswind to the target, the heavier one would need to be launched at a higher initial velocity to keep the "air time" the same as the lighter arrow. The higher speed would cause a difference in drag numbers and throw a wrench in this idea. But do you account for nothing when looking at arrow weight inertia in a crosswind?
