I've registered a healthy number of domains over the years for projects that didn't go anywhere, including most recently a brandable two-syllable domain that contained two search terms that described the business. I didn't park it, and if after it became obvious I didn't need it if anyone genuine had approached, I would have let them have it. I let it go when it expired, and it immediately got snapped up by a domainer who is now asking $K for it. I don't think your suggested approach solves the problem.
