Use Property Setter to override Doctype name?

Is it possible to override a Master Doctype’s display name using a property setter ?
In list view I would like to change the “Contact” doctype link to display the word “Computer” with a different icon. When I create a new contact I would like the page to display “new computer” instead.
Is this possible with property setter? And if so can anyone point me to an example?
If not I will just create a new page instead.

Used to exist at one point, but deprecated for now.

If the DocType means something different, it should be another DocType to maintain semantics and long term maintainability.

Thanks for the reply rmehta. I will create a new doctype as suggested.
