You have trick shots for Grapple, Disarm, and Trip, but no Bull Rush?
Either way, I think I broke this. If there's a Bull Rush trick shot you probably don't need bloodstorm blade, but whatever.

Throw shurikens. You can do the following against more than one person in a single round, I believe, but I'll explain it based on a single (-ish) target.
Round 1) Attack Dude A with your shuriken.
Round 2) Use your swift action to declare your thrown attacks as melee attacks via BB. Now throw at Dude A (2-handed, of course), using Power Attack. This triggers Knockback. Bull rush Dude A into Dude B and get an automatic trip attempt against both of them. If either of them falls down, you get immediate attacks against them (via Improved Trip), which you can make because you threaten them both. This triggers a new Knockback Bull Rush on both of them.
Continue ad nauseum until you pound them into a wall or other obstacle, dealing 8d6 + 3*str mod damage via Dungeoncrasher.
You could do it with Orcish Shotputs to REALLY be bowling, but shurikens are a ton cheaper, and it's hysterical if you 2-hand them.
