From what I read of it, and what people who had read it told me...yeah it would make a better tv show.

The plot is basically this -- a guy has the weird ability to shoot in and out of time. So his relationship with his wife is out of sequence. He meets her as a child, he meets her for the first time after they are married, etc. The River Song/Doctor Relationship is basically The Time Traveler's Wife for kids except with a lot more action and monsters. Also in DW the wife gets to Time Travel too.

It's not surprising the Moffat wants to do it.
