I don't know how well that will work out for some of Apple's proprietary chips. Lots of off the shelf parts, yes, but not everything; maybe not some of the crucial components needed to boot properly.
Like people can reverse engineer things, but till there was a permanent exploit like this, I am sure the effort did not make as much sense. Like you first need an exploit that lets you load a non apple OS. Moreover you hope it effects enough devices that your efforts will be used by a lot people.
Here’s your Android but: WiFi and audio don’t work. That’ll be great.
