Ok, I am going to say it...
IMO (only) L5R 5th Ed, would be wiser to drop its "independent system" and adopt both the DnD 5th Ed, AND the Pathfinder systems. They are not so far apart, and you can column the separate rules/stats in a single book. Go Open Gaming License and cater to a superior market that wants more and is well populated, nobody plays L5R and a lot want to.
DnD5th Ed, desperately needs an "Oriental Adventures" game, and L5R is well respected in its rich culture, artwork and design. I love it, but there is no one around to play it. So why not cater to the biggest market available. Pathfinder also needs an "Oriental Adventure" game also. So L5R 5th Ed, could enter into both markets and sales would explode. Players of the two most populated games would and could buy L5R 5th Ed products, and expand their games into the jade empires. Also, this would allow third-parties, if not L5R to also expand on their design to the neighboring regions, especially Second City.
I entered into L5R during 4th Ed, and a lot of the books were out of print. Also its fan base is very difficult to find, and player are extremely rare. I do not know anyone in NY that plays it. Which is really too bad as the game is one of the best I have ever seen. Accordingly, I would personally enjoy a DnD/Pathfinder system so as to "sweep" my players into Rokugan (sp? - sorry) and enjoy an Oriental style game using L5R background, timeline, storyline, etc.
