If we drop the last consonant and replace "z" with "s" and "w" with "v" (because, they are easily "confused" too) then we can convert to Koremutake those Donomens:

ResourceFunction["KoremutakeConvert"][
   StringReplace[
    ToLowerCase@StringTake[#, {1, -2}], {"z" -> "s", "w" -> "v"}]] & /@ {"DIHAVEJIG", "NUGIBUBAD", "MOKOMEMUL", "VIHUBOMEK", "HIZOJODOF", "JIKUTEBAK", "DUGOFUFIW", "FAZIWATOS", 
  "PULERIBOZ", "NIMUSINOM", "SAZAFOHOD", "ZATAGABED", "SAFEGEVAJ", 
  "KEMEFEFOJ", "WINEJEZUL", "WASISOBOR", "SETEROZIP", "ROBABIZIG", 
  "MAFEZOWUF", "NOTAWITOB"}
