What if P:E had a small but diverse selection of intelligent weapons scattered throughout the land? The kind that come with distinct personalities.
Imagine the witty banter they might have with their wielder, or other party members, or even other intelligent weapons in the party.
The dwarven war-axe with a Minsc-like outlook, or
the bullying spiked club that attempts to intimidate the
introverted dagger who is self-conscious about its size.
They could be a great source of comedy, or indeed tragedy, that resonates throughout the campaign.
Imagine if they had their own personal quests. The short sword in search of the perfect scabbard (a vanity quest). The warhammer determined to reach its rightful owner, only to find they have long passed (what happens next? A new quest?)
They could have all manner of conflicting character traits, similar to the NPCs in BG/BG2.
What would be your ideal intelligent weapon, and what would be its goal?
