Cosmo & Wanda vs Ryuk is fucking hilarious but I wouldn't do it unless as an off-season (idk if off-seasons are a thing when seasons aren't a thing).

Also, no. The contents of the conspiracy board aren't part of the hint, but you do have the right idea in that a Death Note character is being used.
