Of course it is possible although I'd prefer a pre-emptive 'update official part' checkbox rather than a retrospective extra confirmation dialog.
The danger is that someone uploads an entirely different part with an existing number, changes the origin without realising the implications or unwittingly breaks a dependency. This would be especially risky for primitives.
