It would definitely destroy it.
Soldering tips are typically constructed with a core material covered by a protective jacket layer. A big part of the jacket’s purpose is to protect the core from oxidation and erosion. However, for the purposes of heat transfer, it is really thin. That’s why you should never use steel wool or sandpaper (e.g. aluminium oxide) to clean residue off tips — it’s best to use soft brass with tip cleaner if absolutely necessary but even then you have to be gentle. Any kind of ‘well’ or depression you made in the tip would quickly erode out in addition to harming the tip’s heat transfer.
