No need for source changes. Go to Client and Editor -> Resources and there you'll find a client_strings.json file. 
This is a list of all the nomenclature used for windows, stats, chat notices, etc. 
You can edit this any way you like to rearrange what's written in your game.
 
I suggest getting Notepad++ for those edits as it's less of a headache to know what's editable and what's not.
