Exactly, but Tyler was created by the same guy that created the successful GND.

GND is a women from the mind of a man, but Tyler is a man from the mind of a man.  What you need is a Tyler from the mind of a woman, and the woman needs to be skilled at doing the work, just as Blackhearted was with his GND.

Like I said, it's almost as if the ingredients for making an enticing male are top secret.

Her input should be enough as long as she can see the end results.
