I have a requirement to display either of  Standard Page (Account page ) or Customized Standard page (Account Page with few extra custom sections/buttons added) based on a Picklist selection.  Means, I need to enable user to choose Standard Accounts page or Customized Accounts page.

My problem is  can we customize a standard page and save it as another page or do I need to create empty page and code everything the standard page has using VF and add extra customizations.

Appreciate your help.

Also, do we need JavaScript/ VF event like 'onchange'  for displaying different pages?  Appreciate your help.
