I have a subclass extending parent class method via inner() and augment

package C1;
use Moose;

sub html {
    my $this = shift;
    return '<html>' . '<body>' . inner() . '</body>' . '</html>';
}

package C2;
use Moose;

extends 'C1';

augment html => sub { return 'C2'; };

[download]
warn C2->new->html;


# yields
# <html><body>C2</body></html>

I want to add another augmentable method, which content is not mandatory, i.e. I don't want to supply augment in every subclass. 
package C1;
use Moose;

sub html {
    my $this = shift;
    return
          '<html>'
        . $this->head
        . '<body>'
        . inner()
        . '</body>'
        . '</html>';
}

sub head { return '<head>' . (inner() || '') . '</head>'; }

package C2;
use Moose;

extends 'C1';

augment html => sub { return 'C2'; };

But if I don't supply the content of head method in subclass then the content of html method is used:

warn C2->new->html;

# yields
# <html><head>C2</head><body>C2</body></html>

So is it possible to use more than one augmentable method, with some of them having "optional" content?

Thanks for any reply including those: "You should not do this, ..."
