No, you're going to have to start fresh, or make backups of your appdata in remix and transfer it onto something else for safekeeping then install Bliss. Other than not having the UI that Remix and Phoenix have, it's actually much better. It's built on the x86 source with their own updates and such given that it's 7.1.1-7.2, a more up-to-date kernel, I believe they offer both rooted/unrooted versions, and a few other things. Like I said, the only thing missing is the UI system, and to me, that would make them better than any other choices out there in terms of a PC-compatible Android OS.
