Neon tubes have been allowed with a DC-DC high voltage convertor, but must meet all electrical rules and then be inspected. Insulation and safety are the prime issues but leaving broken glass on the field is another. If you can't satisfy all of these concerns, it is better to use the weight for something that plays the game.
The high voltage from one of these convertors is not likely to kill anyone but it does give the gift that keeps on giving as we say in electrical circles. Burns, localized nerve damage and scars are common.
