If Kaiser Wilhelm II also became Tsar of Russia

What if Kaiser Wilhelm II became both German Kaiser and Russian Tsar in 1901?

Religious legitimacy and the degree of political integration come first; access to Russian resources would not instantly produce a unified state.

The premise makes Wilhelm II German Kaiser and Russian Tsar in 1901, but leaves open how closely the two states would be joined. A personal union could preserve separate governments or develop into a more integrated structure. The Russian requirement for an Orthodox ruler conflicts with Wilhelm's Protestant position in Germany, prompting debate about his legitimacy and whether German elites would retain him for the material benefits. German capital and industry could draw on Russian resources, but ministers, administration, and railways would need to connect the territories. That work could absorb the new ruler and change his foreign-policy priorities. The participants disagree over whether such a union would immediately provoke its neighbours or spend years looking inward.
