BQ78350-R1A: using GPIO's as interrupt signals

This application requires an interrupt signal coming from the battery pack to wakeup the main micro when the remaining capacity drops below a determined level. My idea is to use one of the GPIO's in LED mode, program the percentage of state-of-charge for that particular LED, and connect it to the interrupt pin of the micro. My problem is that the LED is only active after a falling transition on the nDISP pin. I could place a timer such as the TPL5110 to periodically generate transitions on nDISP so the LED pin is always active. Do you think that is a plausible solution? Do you have any other ideas on how to generate an interrupt based on state-of-charge?

Thanks!
