A British crown would magnify Frederick the Great's war

What if Frederick the Great inherited the British crown during the Seven Years' War?

British money and sea power would strengthen Prussia, but Frederick's governing style would create severe conflict with Parliament and the British constitutional settlement.

Inheriting the British crown would connect Frederick's Prussian army to British credit, trade, and naval reach. Those resources could make the Seven Years' War substantially more favorable to Prussia and its allies. The political union would nevertheless be unstable because Frederick was accustomed to direct monarchical control while British taxation and war policy required parliamentary cooperation. The scenario therefore offers more military power at the price of a serious constitutional struggle over who directs it.
