Removing the sensor from the Gamepad would make some games unplayable, like ZombiU and Lego City Undercover. It can´t be done.
About the sensor bar..... a couple of games make use of it: Nintendoland, Wii Party U, Call of Duty (when playing with Nunchuck), Just Dance (for navigating menus)...... it also can´t be removed.
TVii is optional. People who can´t use it may just delete it, as I did.
I don´t think the options left would make such difference. Besides, Nintendo will probably cut the price of the WiiU again this year
