I have a Drupal's default `User Login` block in `Side bar first` region at the last position. Reference page: http://indiansnakes.org/snakes

The proposed home page has been redesigned and the `User Login` block has to be displayed in the `Footer Fourth` region. Reference Page: http://indiansnakes.org/homepage

So, the `User Login` block should appear in footer fourth only for this new homepage but for the rest of the pages in websites it has to continue to stay in the `Side bar first` region. In normal scenarios if it was a custom block, then I can create a clone of the same block and change the visibility per page / set of pages. But `User Login` block is system defined and it does not allow me to clone or duplicate it.

I tried searching if someone has already addressed this issue but it seems like not. Looking forward for thoughts.

Edit:
Nearest I could find is this: https://drupal.stackexchange.com/questions/17239/change-block-location-on-page-by-page-basis. But the solution there was to create multiple blocks from same view, unfortunately `User Login` is not based out of views for me.
