There are many reasons why Team Work/Merge Won’t Happen

1) LUNI is Dead (not long until the website dies too)
2) DLU is a CLOSED SOURCE Project and doesn’t want their files put up online.
3) Ion/LUR Aren’t really projects that develop LU just servers.
4) If they do merge, there will be a massive argument due to many things.

So just if you are asking if they will merge. Short Answer: No
