I am definitely not an expert but I believe that the 6 gauge wire will overheat if it is trying to carry more current than its rated capacity. I don't think that is a good idea. I suspect that it would still push, or try to push, the 100 amps through but overheat, perhaps to a point of being a fire hazard.
