Sounds pretty cool. Monk is still a little underpowered in E6, as far as I can tell, so I offer you my old version of the E6 Monk. All of its abilities are as normal (bonus feats, still mind, etc.) unless stated otherwise.

AC Bonus When unarmored and unencumbered, the monk adds her Wisdom bonus (if any) to her AC. In addition, a monk gains a +1 bonus to AC at 3rd level. This bonus increases to +2 at 6th level. These bonuses to AC apply even against touch attacks or when the monk is flat-footed. She loses these bonuses when she is immobilized or helpless, when she wears any armor, when she carries a shield, or when she carries a medium or heavy load.
Quickened Flurry At 6th level a Monk is a truly prodigious martial artist. Monks may use their Flurry of Blows ability as a standard attack action instead of as part of a full round attack action.
I decided to alter the Monk’s Unarmed Damage column so that it actually scales. I also altered the Unarmed Speed bonus column for the same reason, but I started Monk with a +5 ft. bonus to speed. I feel that this balances out the Monk a little more, making it perhaps a little more powerful at each level, and without the long waits between ability advancement. Also, the change made to the Flurry of Blows class feature is not overly powerful. It simply gives the Monk a quicker iterative attack than the Fighter, albeit at a lower attack bonus.
EDIT: With Fighter BAB, your Brawler is probably fine, don't know how I missed that on first read-through.
