D. Felipe II of Spain was certainly an opportunist when it came to the English crown, not only after Queen Mary died. He was betrothed to the Princess Elizabeth in 1536 (shortly before Anne Boleyn fell) when England was seeking a rapprochement with Charles V; and again after Maria Manuela died in 1545; and then, as everyone knows sought Elizabeth's hand once Mary was barely cold in the grave. Likewise, he offered D. Carlos for Liz whilst he was married to Mary. Also, Archduke Ferdinand (known for his marriage to Philippine Welser) was also proposed once or twice.
France, eager to offset Habsburg power in Europe, attempted to marry the future Queen Mary off, first to the Dauphin - François III, duc de Bretagne - or Elizabeth off to the duc d'Angoulême. Then, in the next generation they settled on getting Mary Stewart married to the short-lived François II. The marriage was childless, much like that of her cousin's Habsburg match across La Manche.
The challenge, should you choose to accept it, is to have the England and Scotland of the title. The ruler of England or of Scots does not necessarily have to be the same as the ruler of Spain/France/the Empire. Bonus points if England and Scotland don't get united to each other, but remain in a cadet line of the royal families of the title.
