Thanks for your comments.
Although I cannot judge how common it was, having a statue in between the two leaves of the door was not unseen. See for example the following link:http://bibliotheque-numerique.inha.fr/collection/11501-dictionnaire-raisonne-de-l-architecture/
on page 419, 428, etc...
Now you're right that it looks somewhat odd, I wanted to have the pillar behind the statue a bit more visible... should spend some more time experimenting on it.
By the way, the illustrations above come for the "dictionnaire raisonné de l'architecture", written in the XIXth century by Viollet-le-Duc. Although the book (a bit dated) is in French and might not appeal to an English-speaking audience, it's full of gorgeous illustrations. You may find the 10 (!) volumes on the link above or a abridged version in print.
