Now my character has +1/keen sword. He wants to add Collision psionic weapon ability to it. Is it possible? If possible, how he calculate the cost for it? Is it simply an equivalent of +4 weapon (thus, 32,000gp for enchanting in total)? Or shall I pay costs for +1/keen magic weapon and +1/Collision psionic weapon (thus, 8,000 gp + 18,000 gp in total)?
