Unfortunately, what-if history is not allowed in this sub. You could try /r/HistoryWhatIf, or you could try to rephrase your question (perhaps "were there other factors which led to the decline of the United Provinces", or "how influential was the change in the English banking system" or something similar - depending on what exactly you're interested in.)

Sorry, but your submission has been removed because we don't allow hypothetical questions. If possible, please feel free to rephrase the question so that it does not call for such speculation, and resubmit Otherwise, this sort of thing is better suited for /r/HistoryWhatIf.
