Returning to commercials version then rejoining to dev preview

Simple question. Is it possible return L920 back to commercials version, made it update to Cyan and WP 8.1, then rejoining to dev program and update latest developer preview (Update 1)? Everything because of Folders on Start screen.
Thanks.

Yes. I did that.
