You can do it with a PWM splitter cable. Only certain motors may be "doubled up" on a single speed controller; see Table 4-4 under <R42>.

Also, R57 states that "Every relay module, servo, and PWM motor controller shall be connected to a corresponding port." We have, in the past, used PWM outputs to control Spikes, but I am getting the impression that this is illegal per R57. Is my logic correct, or can we still use PWM outputs to control Spikes?

I do not believe you have ever controlled a Spike using a PWM output. The signals are not compatible. Spike relays are controlled using relay outputs.
