I would be Leary of holding the nose on with magnets.
Why? all in flight force is shoving the nose even harder on, about the only time it can pop off is a very rough landing and even then it's not likely, you're not supporting a battery tray or anything, just the light weight fiberglass.
A hard pull on the elevator can pot a lot of side force while the plane is in a high angle of attack, a knife edge pass or slow roll will also put side force on the nose. If you fly on a grass field you could hit a big bump just as you are taking off. I am not sure what the ramifications of the nose not being there while airborne.
Will magnets be ok for this application, possibly, if implemented correctly.
Better safe than sorry.
