There actually was a project like this, called Cycada, but the main dev terminated the project after being hired by Apple. I can only imagine the same is true of anyone working on the other two problems. On the more corporate side, Microsoft had a number of projects such as Astoria (Android emulator) and Islandwood (iOS transpiler) that were supposed to target Windows Phone, but both were canceled as that platform declined.
