The problem is...
Since the author has decided to activate the thread; my thoughts on the subject are the following ...
The problem is, in my opinion, the apparent conceptual misunderstanding,
on this approach to the theme of this thread...
First, the degree of loyalty to Rome, has little relevance in a serious analysis, not prejudiced in this Spanish historic event.
The Esquilache Riots were developed and were circumscribed exclusively to the capital. The riots were triggered by a circumstantial scarcity of bread in Madrid, were unlike the riots or revolutionary upheavals French and similar to many others bread riots to throughout history.
The riots were in essence from a reactionary and xenophobic character to be directed specifically against a minister who was a foreigner, converted in the target of the popular anger at being perceived as solely responsible for the situation of famine ... exempting from liability to the King and of course it wasn't even conceived by the rioters, to challenge the established order and its institutions.
More important it is that the leaders of the mutineers were most likely part of a political operation and /or the mutiny was used by various political factions of the Spanish Court, to achieve the political fall of the minister and the ending of his politics.
Regarding the possibility that it might first come to pass any kind of uprising then this could become an insurrection pre Revolutionary was nonexistent given the socio-political conditions in the Spain of the eighteenth century, it is impossible for a popular uprising to reach occur that could become something similar to what happened in France.

On the previous lines it's evident that the factors mentioned above apart from the lack of political and cultural influence of the Spanish
bourgeoisie or more important in the absence of class consciousness. These are the determining factors, which they were largely absent in this particular historical moment in Spain.
