You could remove the 5V regulator chip or to avoid soldering just clip the leads at the package. Then power the PI directly and supply 24VAC to the OSPi board. I managed to kill the regulator and desoldered it. I set up the 5V supply to the PI from a UPS so I don’t have SD card corruption issues when the power goes off briefly. Works fine – actually an improvement in some ways.
