This might be a crazy question, but has anyone seen or heard of anyone building a stand (kind of like a riser box or something) for an existing stand? Let's say you have a 30" stand, but want to make it taller (say, 40" or so), could you just build another 10" box, sit the 30" stand on top of it, and skin the whole thing so it would look like a single stand? Is this highly unadvisable? Why or why not? Thanks.
