All good as long as the transmissions to the remote storage cannot be inhibited by actions on the aircraft. Unlikely at best. Probably best to retain the physical DFDR on the aircraft as well as a backup.
FDR and CVR boxes were historically provided to provide evidence for crash investigations after an accident, not an attack on the aircraft. Clearly the latter scenario requires protection of the equipment in ways not previously envisaged. As others have said, the pitiful voice storage time really needs addressing too! It needs to be at least greater than the endurance of the aircraft with a full fuel load.
This subject is probably best shifted to Tech Log as not really relevant to the current situation.
