That said, I use orgmode on android (orgzly) and used it on sublime text (orgextended), that's a nice feature. I know one guy who uses emacs and when I heard of lem (https://github.com/lem-project/lem) I told him. (Lem is also in CL)
He was quite enthusiastic of it, but 2 or 3 things were missing at the time, the first of all you guessed it, it's org-mode, second was magit but he could use lem without it and finally it was a plugin manager (but we agreed it is a lot of work).
I don't know what are your plans but I hope I could give you some ideas.
