Now, although many have already pointed out the various difficulties that any children of Charles II will have to face in reaching adulthood ( given the high infant mortality rate of the Spanish Habsburgs, mainly due to a terrible genetic pull, inherited from the Trastámara and the Aviz, and from a Spanish school of medicine, somewhat questionable, not to say terrible compared to their contemporary counterparts ) but overlooking this detail, we must face the fact that, although Louis and Leopold will have some grievances or claims on parts of the Spanish legacy ( mainly Netherlands and Italy ), nothing will compare to the tremendous political chaos that Spain faced between 1690 and 1714 in Otl ( including deep fractures within the court and devastating wars in its territory ) this change alone would be an important step forward for a possible recovery of the kingdom, given that it should be remembered that the main reforms of Otl Philip V were fundamentally based on two things : the centralized government style, trademark of the Bourbons and some timid institutional reforms begun under the last years of Charles II ( for precision in the colonial and economic-administrative fields ) now of course it is still probable that France will end up going to war with Madrid for mere territorial issues, and therefore it could invade Catalonia again to divert part of the limited Spanish resources in that area ( but this could paradoxically become an advantage, given that it could be an opportunity to unify the constituent kingdoms of Castile and Aragon in some areas ) to conclude it is feasible that given the number of children he had with Maria Luisa, some of them will end up serving in Italy ( as a representative of the royal power ) and obviously in the clergy ( perhaps holding a prestigious position in the local ecclesiastical hierarchy or even as prelate of the curia, similarly to Otl Henry I of Portugal ) now as regards a possible marriage match, it depends on how the butterflies will influence the rest of the continent, given that such a scenario would have important effects in the long term ( from changing the situation in England, to the dinastic succession crisis in Austria, to the last period of Sun King ' reign, passing through the political development of the Italian states ect )
