You can never get the same power with less current given a voltage source unless you sustantally increase the efficiency. Power is volts x amps x efficiency. So any motor regardless of size, kv or number of poles drawing less amps to make the same power is somewhat impossible when motors these days are almost 90% efficient and don't go much higher than that.
You can however, use a smaller motor to draw less current at the beginning and have it draw current afterward when power actually matters.
