In that scenario you're headed straight, but you're mostly using front tire grip to slow the car down, and you just won't have as much of it with the outer edges lifted out. Suspension compression under braking load may push the camber out flatter (I'm not sure), but it certainly won't totally correct the problem.

One of the ways you can ease (but not eliminate) the tradeoff is by trading some static negative camber for increased caster (caster being the way the forks lean backwards on an old-school chopper type motorcycle). Caster doesn't do anything to camber in a straight line, but makes the car tend to add more dynamic camber while in a corner. So maybe (random made-up numbers here) if you ideally wanted -4.0 camber in the corner, but that's too much for your straight line braking, maybe you can go -2.5 or -3 on the static camber and add a degree or two of caster so that it still pushes out to the same level as a static setting of 4 in the corner.

There's a tradeoff with caster, too, though. As you get the caster more aggressive, the car resists turning in more - the steering feels (and is) heavier and less responsive.
