You would probably need to modify/write a new roll template(custom sheet). You might be able to modify Aaron's Color Emote script to customize text sent to chat to look similar. Of course, this would only affect chat text. Either option would require a Pro account.(custom sheet, API scripts). Another option might be to use Stylus ( not S tylish )to override the sheet's roll template look. This would only change your view of the roll template. You could share the stylus override among your group so that everyone would see the same output... Do you have a particular sheet in mind that you would like to implement the chat bubble output?
