So it sounds like OP got the point but for future people reading the thread: If you are asking if something is safe, you probably shouldn't do it. Even if something might possibly turn out safe that doubt can lead to some dangerous situations. You could say what if that hole cracks and not pay attention to what is going on around you and boom you hit something or someone. If something wasn't designed with your use in mind, find something that is or just re-kajigger your expectations and use as intended. Be safe always, the won't look all that clean after a crash
