I always thought that if Charles II were to marry a Spanish Infanta and sire heirs that they would of course be in line for the Spanish throne. Assuming there are enough children/grandchildren to spare, he might want to place one on the Spanish throne (after conversion). The English would need some backing from the continent, and the French would be the most natural allies. Assuming that the English heir is senior to Louis XIV's heirs in the line of succession, I imagine that a marriage of the English (let's call him Duke of Cambridge) to a French princess (if there is one), or of the Duke of Anjou to and English princess would attempt to fight Austria and the Netherlands for the Spanish throne.
Austria would still likely attempt to claim the throne due to Archduke Charles being the senior claimant based on the Salic Law.
Does anyone else see the possibility of a Anglo-French alliance in a war of Spanish succession?
