I think the only thing still missing is a way to get rows from RawExcelSheet (which you get from calling GameData.Excel.GetRawSheet()).

ExcelSheet has a constructor for this very reason. You can use new ExcelSheet<RawRow>(rawSheet).GetRow(...). Ideally, if you only want to work with raw rows/subrows, use ExcelModule.GetSheet<RawRow/RawSubrow>(lang, name) explicitly.
