I have an idea for a World War timeline where the conflict would begin in late 1850s with Russians giving assistance to Gwalior and Oudh during the Indian Rebellion which would lead to a tit-for-tat escalation between the two powers that would drag much of the rest of the world into the conflict. The idea was that by the 1860s variations of the American Civil War, the January Uprising, the Franco-Mexican War, the Boshin War, the Risorgimento, the Taiping Rebellion, the New Zealand Wars, and the Tongzhi Hui Revolt would be seen as the many theaters of a single global war. Does this seem even remotely plausible?
