Not an expert on Dutch History even tho I am a Dutchie myself...
But... a stronger Dutch Republic is possible in the 18th century. They were screwed over in the war against the French (fighting a lot gaining less). If they get more benefits after the Spanish War of Succesion, something to earn money from, it will help in the 18th century. For one, getting the trade rights of slavery to Spanish America. That is a lot of income for the WIC which was already a dead weight. Another one is more settlements in the former Spanish Netherlands.
