This may be implausible but...
What if instead of the idea of going west to reach the Orient, Columbus had the idea of going north to reach the Orient, following the logic of using shorter circumpolar routes? I admit the main problem with this idea is tolerating the Arctic cold during the voyage, but hey if there'll be money in it, maybe one will decide it's worth the risk, given preparation for the harsh weather.
I suppose the most likely outcome would be Columbus perishing somewhere in the Arctic and history forgetting him. Columbus's OTL discoveries are butterflied, but the Portuguese would probably bump into Brazil just like in OTL, so Europeans still reach the New World. The idea of Columbus running into Inuit and believing them to be Chinese or Mongols is interesting though...
