 I've seen several tickets that appear related but are either dead or
 include bigger changes compared to what I'm proposing (the most relevant
 being #21062).

 My proposal (including patch):
 1. Introduce `get_template_part_hierarchy( $slug, $name = null );`.
 1. Update `get_header()`, `get_sidebar()`, `get_search_form()`,
 `get_footer()` and `get_template_part()` to use the new function.
 1. Add a `template_part_{$slug}_template_hierarchy` filter to the new
 function so all 5 general template functions' results are filterable.

 What these changes achieve:
 1. Provide a way to filter the location of header.php, sidebar.php,
 searchform.php, footer.php and any file loaded by `get_template_part()`
 1. Reduce code duplication (all metioned functions had the same $slug +
 $name logic to create a $templates array)

 Also, @MikeSchinkel has mentioned a few benefits and arguments for why
 such a filter is beneficial:
