Dear Nithin,
You wanted to replace productive employees with non-productive ones. Good initiative; nevertheless, have you defined productivity levels for all the levels? Have you conducted a study on low productivity? What is the nature of your industry? What is your finished product or service? What is the ratio of productive and unproductive workers?
If you wish to remove the non-productive workers, then what would be the replacement cost, and what if the newcomer is as unproductive as the old one? Therefore, do you have proper recruitment standards well in place?
Earlier, I have given two replies to posts similar to yours. Click the following links to refer to those:

If you wish to improve productivity, then measure the process turnaround time of various processes and costs associated with each process. The removal of people should be the last option.
Thanks,
Dinesh Divekar
