Is it okay to run one motor in a two motor transmission?

It looks like you received good advise from others already on most points so I'll address your last question...

Do not do this.

The Spike is not a mechanical relay, but (I believe) it is a solid state relay. The spike is intended to run at a full 12 volts. The Victor would put out a variable voltage which is, in fact, a chopped DC waveform. The electronics in the Spike would not likely survive. Moreover, the Victor can put out negative voltage (reverse). This would definitely fry the Spike.

Whatever thread or white-paper you saw gave you bad advice.
