I think it could work, but that's up to Google. Google prefers HTTPS links (if you don't force HTTPS on your site the secure links will be indexed, not the plain ones), however the most important thing is to keep the links valid.
Even if the user clicks on https://whatever, as long as it redirects to the same page http://whatever, you are safe. The user is happy, your search result is valid and everybody wins. I suspect that with the time Google will understand that it has to use the plain version instead of the secure one.
