And here goes some code. Place this on site/ready.php (or create a module from it) and edit the first lines to your liking:

 

/*************************/
/******* EDIT HERE *******/
/*************************/

// ID of the page where the custom content is
$this->pageID = 1;

// name of the field where the custom content is
$this->fieldName = 'body';

// name of html tag and id from the parent of the custom content on the 505 file
$this->elementTag = 'div';
$this->elementID = 'message';

/*************************/
/******* END EDIT ********/
/*************************/


// regex to get the contents of parent element
$this->regex = '/(<'.$this->elementTag.'\sid=("|\')?'.$this->elementID.'("|\')?>)([^<]|<.+>.*<\/.+>)+(<\/'.$this->elementTag.'>)/i';

// On save the content of the field on the 505.html file
$this->addHookAfter('Pages::saved', function(HookEvent $event) {
  
    $page = $event->arguments[0];

    if($page->id !== $this->pageID) return;

    $file = wire('config')->paths->templates . '/errors/500.html';

    $content = file_get_contents($file);
    $field = $this->fieldName;

    $content = preg_replace($this->regex, '$1'.$page->$field.'$3', $content);

    file_put_contents($file, $content);

});

// On render the edit page, save the content of 505.html file on the field to show it
$this->addHookBefore("ProcessPageEdit::buildFormContent", function(HookEvent $event) {
  
    $page = $event->object->getPage();

    if($page->id !== $this->pageID) return;

    $file = wire('config')->paths->templates . '/errors/500.html';

    $content = file_get_contents($file);

    preg_match($this->regex, $content, $matches);

    if($matches) {

        $page->of(false);
        $field = $this->fieldName;
        $page->$field = $matches[0];
        $page->save($this->fieldName);

    }

});

 

The above code assumes that your "505.html" file has a <div> with the id "message" in it, you just have to adapt it to yours.

Thanks @diogo  for this.
