Use glass bottles. We used reuse glass soda and beer bottles all the time, part of your charge when purchasing these products was a bottle deposit that would be refunded upon return.
Okay, great, you solved the reuse of material problem.
Now what about the difference in weight your solution creates? The added weight means more fuel consumed in transport, both from bottling to store and during recycling...
I'm not saying your solution isn't better btw, I didn't do the math; just reminding you that it might not be as straightforward as "just do x".
