Sometimes I think, Shinigami King!Light. He'd revolutionize the Shinigami world, bringing in 'jobs', 'money' and internet from the human world. Suddenly, the Shinigami realm is so much more lively that even Ryuk finds it interesting to live there.
Dead!L can go to Hell and take over there. No one can tell him what to do. L has the demon king who tried to order him around over thrown. There isn't food he likes to eat. So, L funds culinary revolution in Hell, including sponsoring air cons, refrigerators, mixers, ovens, etc. Now no one wants to escape Hell because its better there than the human world.
Eventually though, L ends up dealing with the sudden influx of souls caused by Light bringing 'jobs' to the Shinigami Realm. L is once again on the hunt to stop Kira.
