If you go with 8 levels of Fighter and the Dungeoncrasher ACFs you can take both Knockback and Knockdown (qualify for both pretty easily) and 'only' have a Strength of 76...
Now now, that Strength is just terrible. I mean, you can go into Epic Levels and be able to grapple with the best of the Epic creatures... But really, the benefit is being able to just beat people into the ground.
Why do I say this?
Well you get four iterative attacks, the ability to full-round and knock a Colossal target across the room... With a two-handed weapon your Knockback will have a +66 Strength Check for your Bull Rush. Yeah, on every hit you're probably knocking your average beefy warrior type 30-40 feet back, drop the AB into Power Attack with your two-hander, and (if your DM allows slamming via Flight) some very dangerous things can occur.
Oh, and if you need to not Power Attack to hit something with a ridiculous AC? Do 10 or more damage and you trigger a trip attack with the same type of Check.
When you slam someone with your bull rush? 8d6 extra damage.
If you just wanna take 2 levels of Fighter you will still do 4d6 on that Rush, which is nothing to sneeze at for 2 levels worth of entry, the bonus feats provided to get you there, and get to use your iterative checks for Mighty Swings with those 10 levels of War Hulk.
Of course you will also get additional Break DC checks for doors and walls, and with your ridiculous Break DCs you have made it completely moot to have a Rogue in the party... Because, well, you will have the break DC of an atom bomb doing steroids whose mother was insulted by your target.
Personally? I'd go with the 4 feats that allow me to turn every attack into a status effect or movement, pretty much guaranteeing you can manipulate your targets into walls, flanking positions, etc. Also, screw Hulk... You will be more Sauron (from 1:00 on)
