If a named item with an augment is feed to a Sentient Weapon, maybe have a warning appear: "Named item contains a regular augment! Are you sure you want to consume the named item?"
Could possibly get more sentient XP with augments fitted.
I think named quest rewards from Storm Horns and Wheloon and possibly others (event named items Crystal Cove etc), should also be able to be feed to Sentient weapons.
