How to create another Front Page and switch between the two? (in dev process)
You can use context http://drupal.org/project/context to achieve this.  You can filter on the path and then add blocks to that specific page.

But you will need a holder page.  Sometimes I create a holder content type and then modify the node template to not display anything or just the title.  Then I can attach any view/block or w/e to it.  So that piece of content is just a "holder".
