That would lead to a more powerful China, but perhaps an unrecognizable one. You can get a fair result simply by eliminating Ci Xi, usually called the Dowager Empress. She was a political genius who systematically eviscerated the Qing state.
When she produced the Emperor's only male offspring, he raised her from concubine to Empress (despite already having an Empress). She encouraged the Emperor to use alcohol and opium to excess and neglect affairs of state, which eventually killed him. She encouraged the same behavior in her son the Emperor as his Regent, culminating in opium overdose at the age of 19. While she ruled China she systematically executed officials who displayed competence and charisma while elevating those strikingly lacking in either; she understood that she was dead if any remotely competent male of noble birth arrived on the political scene, and took pains to see that there was no such person in all China. She pursued no bold policies and gave only lukewarm support to any suggestion, because success anwhere could produce a rival. By her death in 1908 she had created the only state in human history in which the more money and lives squandered and lost by an official, the faster his promotion. Qing China could not survive her.
Without her, the Qing state limps on. Even disdainful of outside knowledge and thoroughly riddled with opium, China is simply too big to avoid becoming a Great Power. It took an evil genius to take them down.
