You probably could on the drivers side, if that's where your leak is. On the pass. side, there's really no good way to get to it without the dash out. The only reason I done it the way I talked about, was because I already had my whole dash out for some other stuff. Looks aren't really important. Once everything is back together, you can't see any of it. Heck the factory job looks like crap. I guess since we're having this thread, it works like crap too.
