If you start giving stuff like lances and longbows the AP tag, you're eroding the point of the tag in the first place, which is to differentiate weapons. Lances are not niche anti armour weapons in dom3, they are simply high damage weapons (which often makes them a good choice vs high prot units). A crossbow is a good choice vs armour, but much less of a good choice vs an unarmoured high hp unit, where you could be using shortbows, longbows, javs etc. It may not be completely realistic, but it makes for better gameplay and is intuitive.

You could mod maces etc to give secondary fatigue damage, but unless you make it something like AP rather than AN fatige damage and have a lowish value on it, they're going to be far too good against thugs etc. I don't want to see 20 peasants with clubs phasing a 28 prot cyclops just because they can't afford swords.
