Run bespoke code from SRAM after wake up from Deep sleep

We have a requirement that, the system should do monitor volatages at 2 ADC input pins and we need to flash led for short duration (say 1.5 sec) in every 5 second.

To do this, we do not want system to wake up completely. So, In order to achieve minimal power can we run program from internal SRAM after wake up, do monitoring and flash LED then go back to Deep sleep again. And also we need to run this monitoring activity at minimal frequency say 24MHz from external clock using bypass mode of core pll. So, that power consumption during this active state should be less then 10mA (only CPU).

Please let me know the remaining foot print in SRAM, available for code I can add. We are SDK 7.0 on BBB.
What all factors I need to consider to achieve my target.
How shoudl I calculate power theoritically for above situation. Just want to check, that Can I meet my power number.
