After very careful research it seems that resetting using the BBB on a hard hang would be best accomplished by resetting the PMIC pin 44.
I misspoke about the SYS_RESETn is brought on the p9 ( LOL ) I Meant to say PMIC_PGOOD for a hard reset of processor. But its not an open drain signal so WireORing a WD reset to the pin is not wise. But it seems that the PMIC reset would give the board a cold reset without pulling the power plug, USB or in case it has a battery cape somehow disconnecting the battery. As per the PMIC datasheet. "Pull this pin low and the PMIC will shut down, and after 1s power- up in its default state." Well anyway a test point on that pin would be sweet for a hang proof BBB with the addition of an external WDT IC.
