Is it possible to parse the username and replace parts of the string?

Hi,

We are thinking of creative ways to display users with the same name like appending something that would uniquely identify them. We're pulling users from multiple sources so we can't guarantee that the username will be unique.

ex:

UserX_Apple
UserX_Orange

Is there a way to parse it and display like an image of the fruit beside UserX?

Thanks!
