If i understand your question correct, you want to swap sensors / input devices on the fly ?
It cold be possible, but only if the sensors / input devices act in the same way. Analog input read resistive devices like potentiometers, or devices that send out a voltage between 0 and 5 volts.
Some sensors are read in a different way.
If all your sensors are in the first group, then technically you coild swap the on the fly, but there would probably be issues with sacling amd converting the input.
