You can do that on your site. You have access to the admin language string editor. 
My 2c: I'd prefer "Staff" and "Personal". I don't need my name on the tab, and it would feel weird. Sorta like talking to yourself or something. Kinda nutty. I'd be thinking "No I'm not there. I'm here and looking at that imposter which is only button but thinks it's me". 
Personal fits better IMO, because it's my personal stuff (Pm's and profile).
Or, we could use the title I suggested back at SMF once: My Shiznit instead of My Messages.
BTW, current array code looks like this:
// All the buttons we can possible want and then some, try pulling the final list of buttons from cache first.
if (($menu_buttons = cache_get_data('menu_buttons-' . implode('_', $user_info['groups']) . '-' . $user_info['language'], $cacheTime)) === null || time() - $cacheTime <= $modSettings['settings_updated'])

There are a few stray details to clean up, but it's basically sorted.
