    Excellent.

    It sounds like your library should be more efficient. Perhaps I should consider yours instead. AND it might be a good idea to use CS for touch as well.

    SPI chip select

    Can anyone explain why on the ili9341 the LCD must use one of the SPI CS lines but the touch digitizer does not? That indicates to me that I should be able to use any data line for the LCD as well.
