Jimbojimma, unless you have a tight time schedule, you might consider walking Via Canterbury, then following the Via Francigena as far as, perhaps, Précy-Saint-Martin. You will then be less than 90 miles/150 km from Vézelay. From Précy-Saint-Martin, you can walk through the Forêt d'Orient natural park, and then will pass interesting small towns such as Chaorce, well known for its cheese and for the wonderful medieval statues in the church crypt. On reaching Vézelay, you can follow the Voie de Vézelay, of course, and then the Camino Francés.
As an alternative to the Francés, you could turn northwards from Saint-Jean-Pied-de-Port on the Irún Link, to reach the start of the Camino del Norte. Or you could turn northwards from Pamplona onto the Via Verde Plazaola to San Sebastián, joining the Norte there. Both the links to the Norte make for fabulous walking of about four days. On the Norte, you later have the choice of the Primitivo, as you no doubt know.
A somewhat long way around, of course, but some excellent walking and great variety. If you would like information about the two links mentioned above, message me and I will give you the necessary details.
Whatever you decide, buen Camino! Tom
