It might work if you are starting with a Roadmaster or a Next or some similar low carbon steel department store bike. If you're starting with a quality frame the tubing walls are so thin that you probably won't be able to drill a smooth, round hole. If your hole isn't nice and round, it'll create stress risers - that's a bad thing.
