yes, but it just moves the needle a bit, if you lose 1 of the 1GB parts in totality, you also can't recover, so it really depends in on your error model you are trying to protect from.
In practice a DVD like PI/PO model would be the best for many people (protect the 1GB parts like you said with 5-10% redundancy, and then protect all 100 1GB parts together with 5-10% redundancy. the PI will repair as much as it can at the 1GB size, while the PO will be able to repair 1GB blocks that can't be repaired otherwise.
It be interesting if Par2 or something like it could implement it natively without people having to hack together their own one off solutions.
