I was hoping to playtest this guy before the test was over, but it's not likely to happen.

Martial Maneuvers (Ex): At 1st level, a brawler can spend a move action to gain the benefit of a combat feat she doesn’t possess for 1 minute. The brawler must otherwise meet all the feat’s prerequisites. She may use this ability a number of times per day equal to half her brawler level (minimum 1).
If this ability is triggered before the duration expires, the brawler loses the previous combat feat and gains a new one in its place.
If a combat feat has a daily use limitation (such as Stunning Fist), any uses of that combat feat while using this ability count toward that feat’s daily limit.
At 6th level, a brawler can use this ability to gain the benefit of two combat feats at the same time. She may select one feat as a swift action or two feats as a move action. She may use one of these feats to meet a prerequisite of the second feat. Each feat selected counts toward her daily uses of this ability.
At 10th level, a brawler can use this ability to gain the benefit of three combat feats at the same time. She may select one feat as a free action, two feats as a swift action, or three feats as a move action. She may use one of the feats to meet a prerequisite of the second and third feats, and use the second feat to meet a prerequisite of the third feat. Each feat selected counts toward her daily uses of this ability.
I tried to use only core and the Advanced Class Guide, but had to take Brawling Armor because it's so good for brawlers. Indeed, it partially erases the accuracy gap with a dual-wielding fighter (assuming two short swords or other paired weapons, and not a longsword/short sword combo).
Despite having played Pathfinder on and off for years, I didn't know all the physical stat boosters took the same slot. I had to give up on gloves of Dexterity. The brawler has worse-than-expected AC. (This also causes me to wonder how a fighter takes advantage of Armor Mastery. Maybe less of a brawler issue than a stat-boosting item issue.)
