How about (temporarily) replacing the constructor with your own?

{
    my $old_constructor = \&Backend::new;
    local *Backend::new = sub {
        $old_constructor->( @_, 'my', 'additional', 'args' );
    };
    uf_method();
}

You could/should maybe guard against the module version(s) just in case a/your patch to the useful module gets accepted...
