Max Melee power for a non Barb?

[IdontKare]

So, I was planning on making an 18ftr/2monk again with the new weapon die (looking at you Torn 5[1d12+6]) to stack up really high multipliers and started wondering how i could max out Melee Power on the build. This is what I came up with (please excuse my poor formating)

Epic Lvl 30
Arborea 20
Kensai 40
Henshin 3
Harper 9
WarForged 15
Weapon Focus/Spec 10
THF 6
Opp Atk 20
ActionBoost 30
Destiny 60(gmof) or 88(LD)
L. Ring of prowess 8
Profane 20 (Adherent)
Artifact 20 (Crypt Raider)
Sentient Weapon 20 (5 Peice Prowess 10, 2 Melee power rares 5 each)
Sentient Weapon Action Boost 75 (Prowess)
Mythic Bonus 22 (6 from rings, 3 from gloves 3 from belt, 3 from trinket, 3 from goggles, 4 from weapon)
Max 408[293 no boost] (436 LD [231 no boost])

anyone see anything I may have missed?
