This is exactly what we used in this situation, as mentioned before we
have wrapper classes with use lib/base to get at the shared code and
then in the shared base controller we setup the alternate TT search
paths.

sub apath : Chained('/') : CaptureArgs(0) {     
    my ( $self, $c ) = @_;
    $c->stash->{'additional_template_paths'} =
['/path/to/shared/templates'];
    return 1; 
}

The good thing about this for us is that we can override the path in the
child controller.

sub apath : PathPart('different/path') Chained('/') CaptureArgs(0) {
    my ( $self, $c ) = @_;
    $self->NEXT::apath($c);
}

This has allowed us to have the same code for a number of sites with
different urls and site specific stuff kept in the respective child
controllers.
