I've heard that some people are making the nosecone ejectable (with a kevlar shock cord), and having good results getting them back. I suspect though you'd need to add a thrust block to keep the motor from blowing through the body tube, and to give you your tether point. You'd also probably end up by needing to thin down the nosecone's shoulder to get everything to fit.

Their reasoning is that when the ejection event occurs, the rocket is near apogee, and it gets fired off in whatever direction the rocket was pointed in at the moment. With the nose popping off, it's less likely to go too far that way.
