brushless speed controller work on a motor w/ brushes (DC) ?



That doesn't sound right. A normal DC motor will invert the connections to the rotor as it spins so you can feed it with a constant DC voltage. A brushless DC motor won't so the driver needs to constantly invert the polarity of the signal sent to each phase. I don't see any way you can use a driver that is generating an AC signal to drive a normal DC brush motor - no matter what feedback signals you send it.

Many drivers select which phase is active based on hall effect feedback sensors in the motor. If those feedback inputs were instead hardwired such a driver would not produce an AC signal on its own. You are right that this won't work for open loop drivers.
