You right, but you could still add some re-balance. I mean : if you wear blade runners your body weight is increased and so the fuel consumption of you jetpack is higher, the takeoff momentum is slower and so on, it can be translated into complex game mechanics which consider multiple variables for many aspects of the whole game. This also depends on "how" someone wants to implement the challange itself, imho.
However, I'm pretty sure this as been asked in many different ways already (referring to the ability to wear multiple equipment pieces at once)
