I am sure it is possible.. but with the way chameleons drink I am sure that you would waste a whole lot of money trying If you could just squeeze a few drops in a bowl it would be different, but trying to place enough in a dripper or mister so that the chameleon would get the correct amount would take a massive amount. Also, monitoring the intake of the vitamins would be virtually impossible since some chameleons seem to drink sporadically.
You are probably ok to cut-out the supplements her while she is not eating. If she continues to not eat for a week after you moved her to her new enclosure then you have something else to sort out that is keeping her from eating.
