VESC to test e-Bike motor and car alternator as Torque Load..?

Need some expert advice on doing Torque Loading a BLDC motor Under Test.

I am working on a project where we need to characterize the e-bike hub motors and other motors of similar kind. The DUT (Device Under Test) will be driven by VESC.  To load the DUT i have used  Magentic Particle clutches in past.

But this time i would like to keep the cost down and use an car alternator to control the loading . The plan is to build a PWM circuit to throttle the 12V going to the stator. The voltage and current generated will be dumped into a bank of power resistors.I was wondering if this will give me good linear control over the torque range a alternator unit can provide. Is that an idea worth trying. I would appreciate any feebback on this idea. Thanks.
