No, you really need a type1 font. 

The problem here is not on the metapost side, but in finding the actual file.
Mplib’s finder callback and kpse’s find_file() do not agree on the search type name
for fonts (most all of kpse types are simply file extensions, but more descriptive names). 

In this case, mplib asks for ‘pfb’ but kpse wants ’type1 fonts’.

local function finder(name, mode, ftype)
   if mode == "w" then
  return name
   else
       if ftype == 'pfb' then ftype='type1 fonts' end
       return  mpkpse:find_file(name,ftype)
   end
end
