Reblogging to preserve this DC/MK rabbit hole.
So between google-fu and E-J dictionary, I have figured out that “What would Edogawa Conan do?” is “Edogawa Conan wa nani o surudarou” and would acronym as EKOWANAOSU. Six kana, to fit on the middle three fingers of each hand, and divided across hands as E-KO-WA NA-O-SU. Which also happens to mean “E. Ko. repairs/fixes/corrects/heals”.
(Help help the DCMK prison population is deifying Edogawa Conan.) (Also they are punning him.)
