The first pp has (say) 123456789; the replacement (if orig is lost) would be 123456789-1 (or 123456789A) [the issuance of a pp with a suffix, would invalidate all previous pps--passcontrol agents would know this when they scan a pp on entry/exit.]
There are problems that may arise from such an approach, at least if the passport is to have fidelity to the purpose of further facilitating travel across jurisdictions.
