I don't think that'd be a problem. Just make sure you pay attention to how the drawer fronts on the cabinet you find are attached to the body of the drawer. If it looks like something you could do with screws into wood, you're good--except that you have to remember the wooden fronts will be much heavier than the aluminum that's on most filing cabinets. If you get a wooden filing cabinet (sometimes you'll find these at antique or architectural salvage stores, or you could get a cheapy particle board/laminate one), that'll be less of an issue and the attachment should be suitable for wood.
