Yes, Active Blade Twist will provide many significant advantages.
Another advantage of ABT can be seen on the retreating blades in the above sketch. The root ends of these retreating blades are generating negative lift.
With ABT the tips of these blades can continue to generate positive lift (from positive pitch) PLUS the roots of these blade can be given a negative pitch, which with the reverse air flow will generate positive lift, instead of the shown negative lift.
