In non RC applications there have been brushless motors designed as direct replacements for brushed motors. I was curious as to why this has not been tried for RC if possible.

New 12 Volt, 2-Wire, Brushless DC Motor
Servo Magnetics Inc. - Canoga Park, CA; A new compact low inertia, 12 volt, 2-wire brushless DC motor has been designed to facilitate the simplicity of drop-in replacement of a conventional brush motor where long life and quiet operation are essential. The motor is shown with double-ended shafts however; single-ended shaft configurations are also available. The motor is designed to sustain applications where the motor will see high-vibration loads such as cyclical shaft loading conditions. The low voltage design is well suited for portable or battery operated applications. At 12 volts, this compact 31mm diameter by 62mm long, design can produce up to 20 watts. A variety of electrical and mechanical options are available including windings for specific power requirements, as well as custom mounting configurations.
This 2-wire brushless motor has built-in electronics that give the advantage of a compact package size while offering quiet, efficient and smooth operation. The 2-Wire brushless motor can easily upgrade your brushed motor applications by simply changing just the motor. You minimize the weight and complexity of the cabling and eliminate any confusion about motor phase connections.
There are more examples out there...I am just curious
