I don't know, that's actually not a bad start.
A barbarian who multiclasses into Fist of the Forest (Complete Champion) and possibly Frostrager (Frostburn) could actually be quite good at punching bad guys in the schnoz.
Maybe something like...
Dwarf, Bear Totem Barbarian 3/Warblade 2/Fist of the Forest 3/Deepwarden 2/Frostrager 5
FEATS:
1- Power Attack, Toughness*
2- Improved Grapple*
3- Improved Unarmed Strike, Great Fortitude*
6- Endurance
9- Frozen Berserker
12- Superior Unarmed Strike
15- Snap Kick
*Bonus feat from Bear Totem barbarian
...and fill in the last five levels however you'd like. I suggest more Warblade.
It won't have anywhere near the damage output of an ubercharger, but it'll deal respectable damage with its unarmed strikes, enough to stay in a mid-tier group without feeling useless. Plus you'll have excellent AC, with Con to AC twice and +6 natural armor coming from Frostrager.
