This is the part I'm concerned about, although I'm stupid about modding, and not very familiar with how some of these stats work. If arrow damage drops below a certain threshold value, does that mean it could cause no damage at all? If everything scales to any value, this wouldn't be a problem, but I worry about threshold situations like that.

You'd need to be motivated to go through this for each unit, but it's easily within the realm of possibility, and I for one would love to see the results of such an undertaking. Note that the attack value may need to be played with, as we have no clear idea exactly how it is applied, and applying a ratio to it may in fact not change the unit's kill rate by that ratio.
Yeah, I'd like to see the results of this also.
