Removal of laser cut emblem on a lead crystal award

Is it possible to sand and repolish lead crystal? Retired, downsizing and would like to donate /repurpose several crystal corporate awards to a local organization to use as recognition for volunteers. I would like to remove a laser etched emblem etched on one facet. Is a pentagonally shaped surface approximately 2”x4”. The etching is shallow- a few micrometers deep. I can’t think of a way to fill the etching and then polish either.
