Maybe the decabrist revolution in Russia could be a success, the lack of stability in the country would allow Sweden to secure Finland. There could aldo be some Polish rebirth event, where Poland is reborn out of Cracow, this could be also due the success of the decabrist revolution. I also was working on a set of events for Texas (if he would stay independent),in which he could sign an "liberation pact" with the US, that would mean that the states do not pretend on TEX territories and vice versa. This pact would also guarantee military aid for TEX in case it would try to secure Mexico. But in this version Texas could try to secure Spanish territories in North America. If the confederacy and Texas do exist, the abolishment of slavery in TEX could lead into an second war between USA and CSA. For the Ottoman there could be a set of events "Rebirth of the Arabic halifat", and, when it would be reborn, the halifat could pretend on Iberia (Spain). About the events with mongols invading Japan and the Japanese would assimilate them, perhaps, the Japanese colonisation of Syberia, then? More than that: A part of America could belong to Japan (one of my craziest fantasies was that Japan with China, Korea and Manchuria would form Oceania

). Could also add Indian revolt with Japan supporting the rebels.
