You should normally just create  a new TV template by mapping it to your
new HTML template and then switch the selectedt template on the page.
The file name  of the template does not matter.

If you create a new data structure, you have to make sure to keep the
fields names.

Why: TV uses 3 xml structures for it's templating process:

1.) The data structure where the field names and their BE and frontend
rendering are defined.
2.) The  mapping xml (TV template object) where each field from the DS
is mapped to some part of the html file.
3) The flexfield xml in the pages table ( or tt_content for FCE's) where
there content is mapped to the names of the data structure.

So, the field names are the essential key for the content mapping.
