It could be possible with enough of work and stuff, but I'm unsure if it can be done "now"
Yeah, it would require a lot of work. Android is open-source software. iOS is closed off by Apple. Even if someone somehow managed to port iOS to even a single Android device, Apple would most likely issue cease-and-desist warnings before suing. And even if iOS ran on Android, the former is programmed to run only on Apple devices. iOS ported to Android would see many random system errors and crashes.
