NB you need to enable SPI mode on some of these devices... As they come configured in dumb mode as a drop in replacement
See [github.com] for how to set the configuration.

With integrated steppers it much harder. you going to have to move the enable,step and direction for each stepper onto a new unused pin.
Then you going to have to get some sort of external drivers boards and wire it all up.
Its should be possible, presuming you don't run out of IO pins. (a quick count shows about 10 free IO's on various expansion ports, enough for 3 axis..)

These 4 pins are just parallel to the onboard-drivers step,dir,enable and gnd pins, so you can't repurpose them by firmware to add a SPI port with them ( maybe other unused pins ?)
You can use them with external drivers that don't need SPI.
