There's a simple solution for Frankie. Since his sprites only appears with Woman Vampire (which it's technically called in Japan, although only in this game), and she only appears in the Mansions, you can limit possible palettes to 5 areas.
When the mansions are loaded into the PPU, there are two possible ones, Death or Carmilla. So her tileset would appear in at least 1 or 2 mansions out of 5 (which would otherwise be Death's set), so use an emulator like FCEU (one with debugging available, for the PPU Viewer), and check which mansions Carmilla's set appears in and use those palettes.
