I wish I could be more scientific with what I'm about to say but..I'm no genius. But I believe such an idea is a possible success because all touch is still a sense of perception from the brain...If you can harden your sub-conscious with such sublimation you can probably have your brain feel more actively to the nerves in your feet...
Re-reading that though, I feel I could try to explain it a lot better...but I do not know how.
Best luck to you though! This is actually a very interesting idea...
