Your challenge, should you choose to accept it, is to regain the Spanish crown for the House of Habsburg by 1750 with a POD after the Treaty of Utrecht.
Well one way is to have Philip V and his young family assassinated (by whom I don't know, perhaps Catalan Separatists?) before the Austrians and French sign the Treaties of Rastatt and Baden. This in effect levels the Bourbon male line and leaves Charles as the only real contended to the throne.
