Perfectly legal.
But I say, to heck with bastard swords. Play a dwarf and use dwarven waraxes in each hand. No exotic weapon feat required.
Either way, it's a dangerous game you're playing. Taking -4 on every attack can be far more of a pain in the buttocks than most players realize.
Our group just finished a two-session incursion into the local temple in our hometown. A big temple that used to be a fortress years ago. Had more temple guards than the city watch. Clerics everywhere, of course. It's a good temple, strong community values, and a major source of well-being for our town. But the guy running the place was corrupt. We suspected demonic posession (and it turned out we were correct).
But the guards in the temple were our neighbors, good, decent folk doing their job, earning a paycheck. We couldn't just go in full-on-assault and kill all the guards to get to the bad priest.
So we decided to fight non-lethal. Nobody was proficient with non-lethal, so everyone had to take -4 on all our attacks. It was a whiff-fest. Fights that were equal CR to our level were very risky. Our final battle, the group of us (5 PCs levels 6 and 7) faced two level 10 guard-captains in very heavy armor. We almost died. Two PCs were in negatives before the fight was over, and it was a last-ditch Hold Person spell that turned the tide.
So yeah, taking -4 on every attack roll is amazingly punishing. It turns what should have been normal CR battles into real headaches, what should have been a headache into a near-TPK.
Don't take those penalties lightly - remember the TWF penalties stack with everything else, so imagine how useless this character would be at -8/-8 when YOU have to go non-lethal combat...
