how can I create duplicate cody of modules ?

how can I create duplicate copy of modules like (newsletter subscription box),  (Information) & (Product Tags) ?

I know that I can use same modules also but I want to make design changes in modules according to different pages. If I change design of any module, the change will affect all pages where that module exists. That is why I want to create duplicate copy.

Can anyone provide steps for this and how to link up in master page?

Is this right?

If I want to create duplicate copy of (newsletter subscription box).

I go to Newsletter/NewsletterBox.chtml

I Right click on NewsletterBox.chtml, copy it and paste is in the same folder (newsletter). Rename it as NewNewsletterBox.chtml. In TwoColumn master page, I add this

@Html.Action("NewNewsletterBox", "Newsletter")
<div class="clear">
        </div>

Is there any controller or .cs file connected with it ? is this fine ? or correct me plz.
