Is this even a possibility? I have the ported OnePlus Launcher, and I know the Pixel Launcher has been ported. But I'm wanting to try out other stock launchers as all without having to switch phones.
No one here. Possibly someone on XDA Forums. But don't count on Touch Wiz (the Samsung launcher) ever getting ported. I don't know one developer who either has never used it or doesn't hate it. To use it is to hate it.
Try Nova Launcher, if you haven't already. You might like it (once you've tried everything you can do with it, which is a lot).
