Interesting idea to copy objects. However, according to SOX, those who have full access to production and development are distinct two groups of people. You cannot push DEV object into PROD like so. (sorry being negative, SOX is good or bad, but if you are not small shop). PROD always refresh DEV so be careful what you push.

I can see the use of any opportunity to push an object, say between two QA platforms, if the script can enhance to do a list of SPs one shot.
