That would be an added technical complication although it does have merit. We used to have PLB with a battery life of about 12 hours IIRC. We were taught to anticipate the time for SAR to reach the area.
There will certainly be a re-evaluation of FDR etc. Will they be ejectable? Is their purpose to mark the crash site as well as record flight conditions?
Maybe there should be a 3rd simple acoustic crash locator beacon.
