I have a couple of pattern suggestions, and I have included links to an excellent website where the original art is all together. I am very interested in the portraits of the Tudors in England, as seen here:
The main site is here:

Henry VIII
http://www.tudor-portraits.com/Henry7.jpg Holbein
http://www.tudor-portraits.com/Henry8.jpg Holbein
Elizabeth I
http://www.tudor-portraits.com/Elizabeth20.jpg The Phoenix portrait
http://www.tudor-portraits.com/Elizabeth22.jpg The Pelican portrait
http://www.tudor-portraits.com/Elizabeth12.jpg The Ermine portrait (my favorite)
http://www.tudor-portraits.com/Elizabeth6.jpg The Armada portrait (1 of 2 - either would be great)
http://www.tudor-portraits.com/Elizabeth14.jpg The Rainbow portrait (my second favorite)
http://www.tudor-portraits.com/Elizabeth7.jpg The Coronation portrait - probably my least favorite.
I hope you consider maybe doing one or more of these. They would make great companion pieces to the tapestries (one of which I'm diligently working on now

)
