Yes it should be smaller at least on status and menu bar as those hook into the window and are no gadgets. Don't know for toolbars, as they normally are a gadget like others as well.
One thing to mention is: The difference OS work a little different with all this stuff. Especially apple has quite strict rules on what is allowed and what not (oversized buttons with few text for example won't be the size you define them etc).
So best thing to do is really test it out.
