gotribe brought up an interesting topic:

Should there be any changes to the WCF and/or other documents to address current concerns in theological development? Here is a brief article addressing changes that are being considered: Revision of the Confession of Faith (Cumberland Presbyterian Church in America). Everyone may enjoy this development as well: Appendix 4 – Westminster Confession

I also know there is a book out there someplace discussing this issue, but I can not remember its name.

Remember the PCA has already changed it for the USA:

Quote
The Presbyterian Church in America received the same Confession and Catechisms as those that were adopted by the first American Presbyterian Assembly of 1789, with two minor exceptions, namely, the deletion of strictures against marrying one's wife's kindred (XXIV,4), and the reference to the Pope as the Antichrist (XXV,6).

Other than these changes, and the American amendments of Chapter XXIII on the civil magistrate (adopted in 1789), this is the Confession and Catechisms as agreed upon by the Assembly of Divines at Westminster which met from 1643-1647. The Caruthers edition of the Confession and Catechisms, which is based upon the original manuscript written by Cornelius Burgess is the Edition presented to and adopted by the First General Assembly of the Presbyterian Church in America.
