QuadSpi as general purpose "parallel" SPI?

I am currently evaluating the i.MX RT1064 and its RT10xx cousins.

I have 4 identical high bandwidth SPI peripherals that I need to control in identical ways (analogous to SIMD), but I need a separate MOSI and MOSI line per each of the four peripheral.  I therefore need 9 lines: 1-CLK, 4-MOSI, 4-MISO with a MISO/MOSI pairs for each peripheral (see attached simple schematic).  Is it possible to map Quad SPI back to a dumb full-duplex mode?  I'm looking to just DMA block of data into memory.

Hi

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
Q1) Is it possible to map Quad SPI back to a dumb full-duplex mode?
-- Actually, I'm not very clear with this question, whether you can explain it.

Have a great day,
TIC
