For PFS can a Everflowing aspergillum have anything added to it?

[Meager Rolmug]

Everflowing Aspergillum

Price 7,805 gp; Aura faint conjuration; CL 5th; Weight 4 lbs.

The holy water in this +1 battle aspergillum never runs dry. However, the water vanishes 1 round after leaving the aspergillum, so it cannot be collected. As a full-round action, the wielder can swing the weapon to dispense a vial's worth of holy water as a ranged touch attack with a maximum range of 10 feet and no range penalty. An everflowing aspergillum counts as a good-aligned weapon for purposes of overcoming damage reduction.

Can I have it made of mithral?
Can I later add the "vicious" magical feature to it?

It's a specific magic weapon, so no to both.

Magic armor and weapons may be upgraded to named versions if they are the same basic material and shape as, and meet but do not exceed the enhancement bonuses of the named versions.
