if you arent trying to build muscle, no reason not too. Only thing is, looks like yu want to do it on "off" days from weight training. I would really think about making sure you have at least 1-2 days a week, where you dont do either cardio or weights, your body will need the break, especially your legs.
Currently I'm doing cardio 2x daily, 5x a week, plus my weight training, and its peeling the weight right off me. But on the 2 off days, my trainer stressed that I take it easy, and let my body heal
