I doubt that it can happen at a reasonable cost.
ABS has to cut into the braking system, so to speak, so that it can modify the amount of braking to any one wheel. It needs a speed sensor at each wheel, the ABS "brain", and a high-amperage circuit. It also should have troubleshooting built in so it can communicate to the OBD port. What all of this means is that it needs to be built into the car, rather than added on.
ABS from older cars were more mechanical in design, but I would not want to try to modify one to fit. The brakes are one of two critical systems, steering being the other, that need to be done right or not at all.
You might not like to hear my opinion, but I'd recommend finding a car with ABS and buying it to replace your 2007.
