A 1/4 Hex Impact Driver will be far more flexible and practical than a 1/4 impact wrench, what you have right now is the same power as an impact driver with a less practical chuck. you should go at least 3/8" for impact wrenches due to the larger motors and torque output for larger jobs.

also there is nothing wrong with having multiples of the same tool, when doing larger projects it helps having 2 different drills with different bits ready to go rather than having to swap them all the time.
