Here is how the forum describes showers. "Shower - Another method of providing water, especially to dehydrated chameleons, is by using a shower. Place a large plant in the tub, aim the shower head against the wall, and run the water so that only a fine mist reaches the chameleon. The water should be room temperature (not hot!). They may drink for up to 30 minutes. Make sure to supervise your chameleon at all times while using this method."
Sounds like you are talking about hand misting with some electrolytes. That doesn't sound unreasonable if its not over done. I've done something similar with hand misting or dripping to stimulate drinking.
