Your tactic only works with the alignment drain disabled, which isn't by default, so in the common case it still doesn't work. But sure, even then you can just buy arrows from evil players even if there's completely no way to get those normally. IMO it's still questionable why only evil players can craft and use those, but that's another topic.

Coming back to the original suggestion: Making those bottles stackable to 16 is not bad in my opinion, because I can't see any downsides there, though those then don't match the default vanilla behaviour anymore  (which could be irritating). I don't think that they make the arrows more OP, because the crafting can already be accelerated with NEI (shift-clicking feature), and having some berry bushes means a nearly infinite supply of those poisoned berries, so the transportation aspect doesn't occur either (so one can really make a lot of arrows with four bottles and a few stacks of berries and arrows. And even if the crafting would take a little longer time - in a PvP situation this doesn't matter, because a player then already has the needed amount of arrows.

Though adjusting that to more drinks/draughts makes those more OP, see above for that.
