Any way to perform SPI transfers to non-flash device with QSPI driver?

NCS 2.6.0, nrf52840
On our board we have attached a QSPI nor-flash as well as a SPI-based OLED display on the same pins.  
 
I'm wondering if there has been any attempt to support non-flash operations with the QSPI driver.  I would like to add a SPI-type child interface for the QSPI driver that provides a standard SPI driver api.  The actual SPI operations could either be through QSPI (if thats possible) or by allowing another SPI peripheral to take control of the pins.   We don't use the XIP features..
