I think it will not work. Your guitars pick up picks up the variation
of the magnetic field because the string moves in the pick ups field.
The strong magnet is already present in the pick up. Adding more
magnets gives forces in that point in the string, what may make it
behave less linear, and sound less.
But what's more important: there is no point is trying to get a higher
output. What usually is needed (yes, I modified my guitar myself) is:
- a good signal to noise ratio
- the desired frequency spectrum giving the desired sound
You can reach this by proper shielding, making sure grounding is the
way it should be, and correct components are chosen. Often the tone
control capacitors are too large.
