You can put any expression into a conditional breakpoint, so anything you can do in the console you can do in a conditional breakpoint.
So, if you're doing this sort of thing once, you can just type it into the console and you're golden. But if you want to modify a stack local variable over and over again every time it is initialized, it's much easier to do in a conditional breakpoint because then it will happen every time that line of code runs, and your debugger never has to pause.
