I just don't know if it would have been as balanced as the Doctor Who special. DW told his own story that crossed time and space. I think the plot line is appropriate that Orcci described, but it could have easily gone over to self-referential that would lack some broad appeal. I'm not the biggest DW fan, but I could certainly appreciate all the different nods in the 50th, while absolutely loving the story. It's a fine balancing act, that I'm not certain that concept was quite there. I'm not disagreeing with nostalgia just that it needs to be balanced with an original story.
