How to theme the edit page of a form and retrieve $form variable from the hook_form_alter into the template for theming purposes?

Question

I have a content type A How can I add custom theme to edit page of that content type A in drupal 7 only for specific role ?
In my module,

function hook_form_alter(&$form,&$form_state,$form_id) {
if (form_id == 'content_type_a') {
global $user;

if (in_array('rad',$user->roles)) {
$form['#theme'][] = 'custom_content_type_a_node_form';
}
}
}

In my template.php file I have the following code

function hook_theme() {
  return array(
    'custom_content_type_a_node_form' => array(
      'variables' => array('form' => NULL),
    );
  );
}

function THEMENAME_custom_content_type_a_node_form($form) {
// When I check here for $form I get an empty value 
// I want to get the $form value derived from the form_alter function's $form //variable . How can I achieve it?




}

How can I retrieve the $form value from the hook_form_alter's $form variable?

Try something like this:

function hook_theme() {
  return array(
    'custom_content_type_a_node_form' => array(
      'render element' => 'form',
    );
  );
}

function THEMENAME_custom_content_type_a_node_form($variables) {
  dpm($variables);
}
