Comment (by sebastian.pisula):

 I haven't control to overwrite meta value via get_post_metadata filter.
 Why? Because I can't check that post has _thumbnail_id.

 In my filter I can check:
 {{{#!php
 <?php
 if (empty ($ post_thumbnail_id)) {
 $post_thumbnail_id = 5;
 }

 return $post_thumbnail_id;
 }}}


 Additional solution is compatibility with has_post_thumbnail function :-)
