Both of these depend on France, let us postulate a truly expansionist French North America with proper encouragement to settlers so they can hang on to Missisipi and New Orleans just as well as they did Canada. Given a major defeat in one of the many 18th century wars Britain could be forced to abandon its North American colonies in order to hang on to its valuble sugar islands.
In India there is the obscure battle of Plassey, if Jones had won (not totally ASB) then the British would have an advantage that would cascade forward when the Carnatic wars came around.
