I'm thinking of doing a TL based around the 1905 Russian Revolution, where Tsar Nicholas has a heart attack or something that takes him out and the Tsarvich becomes Tsar under the recgency of Michael.
Do people think this could have potential or is it silly?
If your TL leads to a butterflies into Alexander Kerensky winning the seat of Government when the Romanov Dynasty topples, then yes. If the Reds still win, then the flow of history remains generally the same.
