I know I'm like two threads late, but check out my forgework document that I made a long while back for making heavily armored, punchman warriors.

There are a set of weapons called Armored Fists that allow you to punch people without needing IUS, as they are martial weapons. They are also light, but that doesn't matter if you go the prodigious two weapon fighting route. There also body wraps which do the same thing, but with less style. If you pick up exotic weapon proficiency (Armored Fist), you also gain a + 1 shield bonus, +2 if you are using wielding two or more armored fists, as well as allowing you to use them as shields.
Then, go into Soulknife, and grab the Augmented Blade Soulknife. Its stackable with Warsoul if you want to be an initiator. Don't forget the free gifted blade, assuming your GM allows it.
Augmented blade does a few things for you. Namely, you get access to heavy armor, and you can get TWF right out the gate as a bonus feat at level 1. You also get a psi crystal, which you can use to gain a +4 to initiative. At 4th level, you can gain access to the Split Crystal blade skill, allowing you to imbue them without going through the pain of enhancing them via gold.
Soul knife has all sorts of goodies, like a blade skill that allows you to poach Deadly Fist blade skills(Such as the Flurry line), but you can check that out yourself.
Gifted blade has a list of powers like thicken skin, force screen, and precognitive defense that all allow you to boost your AC further.
On the Warsoul side, you get Broken Blade naturally, and its a free swap to get Fools Errand. Being psionic, Sleepy goddess is a good grab as well. Combined with all of the above, and you should be a heavily armored, brawling machine.
I hope you see this and it helps, armored brawler user!
