Cheap yes.  Questionable, no not in my book.  I have thought about this a
bunch and think it is a great idea.  Be sure you shield the wires from the
ballast to the bulbs, they can create hellacious TV interference.  Danger,
not if you are qualified and careful.  Good joints, adequate mechanical
protection, good shielding.  That kind of thing.
