A couple of comments: Occult Slayer is considered far behind the other two PrEs in terms of DPS, particularly in epics; FB capstone (Storm's Eye) is insanely OP compared to the other two caps, IMO. And humans are preferred for barbs (and most builds, really), due to extra feat and racial Dmg boost. [Heal amp too, although barbs get plenty of that these days.]
That said, if you want to go the dwarf OS barb route, I say embrace the flavor and go full CON-based like this:

TWF w/axes: for warhammers or picks, take the relevant Imp Crit feat and tweak enhs. Why Spellcraft? The extra Spellpower will boost the cold dmg from Scion of Water; but if you don't plan to take SoW (or intend to HTR first), then you can drop Spellcraft for something else.
