I am afraid that is not possible, the PICAN-M also uses pins 8 and 10 (UART0).
The good news is that the MacArthur HAT project is still alive and we will be sending the first units to beta testers soon. It uses SPI0-1, UART3, and UART5, leaving SPI0-0 and UART0 free to be used by the dAISy HAT, Moitessier HAT (hacked and non-hacked versions), or any HAT that uses those pins. We are working on the documents at the moment and hope to publish all the details in February-March 2023.
