Hi Martin Spichtig
In terms of SPI module, your three devices use the same SPI module, so in your SPI code it shouldn't be any difference or troubles. I just recommend you to check pinout, MK64FN1M0VLL12 device doesn't have some pins that are available in the MK64FX512VDC12, ones of them are some SPI2 pins:

So, please consider this if you are using SPI2 interface.
Hope this information could help you.
Have a great day,
Jorge Alcala
