These are the personal modifications I've made in case you are interested. Note that grapple weapon support is baked into the latest PE that was released (2014-01-07):

-More interrupts that are cascading (Ring of Peace, Quaking Palm, Paralysis)
-Native healthstone usage instead of function call
-OOC buffing
-Grapple Weapon/Ring of Peace for auto disarm
-Automatic Nimble Brew/Tiger's Lust
-Racial selfbuffs (e.g. Blood Fury)
-Diffuse Magic/Dampen Harm support
-Removed unecessary 'exists' checks
