the power vis is a doddle to remove, just unplug, unscrew and carefully pull from the housing, when replacing just make sure the lever sits correctly. the balance one is a bit of an arse to get out due to the brake reservoir being in the way of some of the screws, if you find an easy way let me know as i haven't tried removing it for fear of rounding the screws. as to running with them unplugged i am not too sure about that
