Yessir, it can be done, but it would require 2 limit switches and a mid-range switch, plus some extensive wiring/circuitry, and it would be based on transmission type, so a "universal" setup would be hard to do.

It would also require more than a few mins worth of mounting, since there usually isn't room next to the auto's brake pedal.

The best use I can find for a clutch pedal in a automatic is the same use it has for manuals - neutral.

In the case where you've upgraded your auto to be used EOC-style, use the clutch pedal and key off to coast, start 'er up, let out on the pedal, and you're back in gear.

This could be done with hydraulic automagic transmissions too, but it would require more extensive work, because a hydraulic valve would have to be placed and actuated in the transmission that would allow the pedal to activate the neutral gate in the transmission that allows fluid to bypass the clutches.
