That’s going to make an interesting handling kart. If you think about it… (At least with a rear axle based wheelbase change) you can’t change the wheelbase from one side to the other without putting the rear axle out of square with the chassis. Essentially a permanent rear wheel steering.
I’d experiment with F/L weight split first. Or even offsetting your rear hubs. The other thing to consider is that your axle sprocket is going to be out of square with the motor sprocket
