Actually, inspiration is a player in my group is designing a paladin as a follower of the dawnflower and taking the trait that allows them to add 2 points to damage if a critical hit is confirmed. I was looking for something that could temporarily allow the weapon (scimitar in this case) to be used as a flaming sword. I don't have a problem with the sword being destroyed, but in that case the character would probably be toting around a box full of scimitars. I think something less destructive would still prove useful, perhaps using flaming weapon in this manner would cause a -circumstance penalty to hit and damage for the sword itself, damage from the flame causing 1d3 or 1d4 points of damage and the flame only burns for a very limited time and there is a chance that the weapon gains the broken condition each time the substance is used and ignited on the weapon. Also, it could only be used on steel alloys as anything less would automatically gain the broken condition.
