What you'd ultimately have happen is that the people that were consistently slower, assuming that some were, would eventually just change to the other setup. If they were both at the same performance level, you'd eventually have everyone using the cheapest option. If they end up costing the same and the performance is essentially the same, there won't be much point to it. At least with real race series where there are multiple classes, they have a noticeable difference in performance and looks. It's like running 2 races at the same time on the same track. The concept would work better if it was a TC class paired with a similar performance level pan car class, where the difference is far more than the motor and battery. I think this could actually be pretty cool.
