That's the equivalent of taking a component - say a gearbox - and adding the data tag from a different gearbox. The data plate is surely the identifier for that hull. If the hull is fine, why not use its own data plate. If there is "nothing inherently unsafe" with braking the traceability of the fuselage then no problem to break any other line of traceability.
Anyway could be, should be, etc all of no avail. It is not legal to swap data plates and, if caught, there are therfore consequences.
