It was already confirmed that thy actively avoided, as much as possible, putting "dies" triggers on Legendary creatures. It is why your list is so small and has a fair number of older cards.
I doubt Kokusho makes that much more of a splash. It honestly seems best to just leave him in the graveyard and reanimate him a bunch of times since you are already in black. Why pay 8 mana when you can pay one.
Regardless, I wanted to call out this quote because this doesn't work. The thing putting commanders in the command zone is a State Based Action, not a trigger. And that SBA is handled before Lim-Dul's trigger even makes it to the stack. You can still pay the mana but you won't get anything since the card already changed zones.
