I have a number of customers that come through for work and they have single sided caliper setups. Matter of fact, I had to change a 30” tire on an FLHX today with one. Your ABS sensor is part of the left side wheel bearing so that won’t be affected. With having OEM dual calipers, I think you would need to change the front lower line out to aftermarket. I do believe if you check some aftermarket places, there are single caliper lines that you can swap in.
