I am working with some entities that get themed with a #theme property in a renderable array. I would like to add some theme suggestions, so the entity could be rendered differently if a template is available. Something like this...
$element = array(
'#theme' => 'entity',
'#theme_hook_suggestions' => array('some_other_function'),
However, this doesn't seem to work. Can anyone confirm or deny whether such a thing is even possible? I have a feeling this is just wishful thinking.
