I actively discourage on deck batters from trying to retrieve discarded equipment during ongoing play.
I would not do this. I don't like the idea of telling a player what to do or what not to do, because the moment you do that, you A) could be considered coaching them and B) may assume some amount of liability should they carry out your instructions, only to have someone end up getting injured.
Catchers have been kicking bats out of the area around home plate for decades, and on-deck batters have been retrieving those bats for just as long. I let them handle it.
