No, not for determining torque or power. If I take a motor wound bifilar with two wires of the same gauge (like a ROAR-approved 17.5T with 20 gauge wire), then cut one of the wires, the Kv remains essentially constant, but the torque and power both drop by a factor of two.
If you mean "Kv and resistance are sufficient" then I think you are correct.

Reason: Changed "Kv, number of turns, Y or delta wind, and resistance" to "Kv and resistance"
