Getting back to the original question about paladins being able to create more than just a few items listed...
One way is detailed in Weapons of Legacy (sort of), and in fiction: Use.
There are magic items in legend and fiction that were not created intentionally. Instead, by their use, they became imbued with special powers. So, a paladin who makes a habit of slaying demons might find his sword, tempered in their ichor, has become a Demonbane sword.
Such a system has some advantages- instead of XP, the main cost is time. The enchantment becomes, in effect, another treasure, and no "mystic process" need be involved.
