Sure you could, just like you could bump up the dice size for fighting-types or any other number of DM fixes that aren't even hard. My assertion was that the base RAW game favors swords* (and I definitely feel that it does), and that there are indeed DMs who play it "by the book", either for a sense of novelty or simply a misguided notion of that being how the game or AP is to be run. To reiterate, if I had my wish then it'd be a moot discussion in the first place because all weapons would be reasonably balanced against each other from the get go, or at least have a few valuable niche applications.
*Moreso with my previous arguments that most campaigns will have magic items based on their prevalence in virtually all APs. If you have no magic items at all then obviously the swords are less favored, since they don't have all the legacy enchantment stuff.
