Now I have similar code as you write. I think, better idea will be if  'pass()' has 2 options. 
1) such as now. call pass() process next route.
2) put to 'pass' route method, which I want to next process, such as "pass('/index')"

I found some methods which make what I want, but I think that idea of 'pass' method which has 2 options its better. 

sub pass_own {
   my $name = shift || return;
   foreach my $app ( Dancer::App->applications ) {
       my $routes = $app->{registry}->{routes};
       # push the static get routes into an array.
       foreach my $k ( @{ $routes->{get} } ) {
           if (ref($k->{pattern}) !~ m/HASH/i && ($k->{pattern} eq $name)) {
               return $k->{code}();
           }
       }
  }
}

Cheers Igor
