Can lift be increased by increasing the angle of incidence of the wing?
Yes.  Angle of Attack is included in the Lift formula.  Lift generally increases with angle of attack in a linear fashion until AOA reaches stall.  This is why it is not a good idea to fly at too high an AOA.  Better to increase Velocity.  Lift increases with Velocity squared.

The Navy Vought F-8 Crusader had a "variable incidence wing" that was raised to a higher pitch relative to the fuselage for take-off and landing.  Interesting to note the variable incidence wing would also improve forward visibility on landing because the fuselage nose would have a lower pitch to the horizon while the wing was at a given angle of attack.  Trailing edge flaps also raise the wing chord incidence to the fuselage with similar benefits.

While in flight, most planes simply pitch the entire plane with the elevator to increase Angle of Attack.
