not really on my opinion.the wax may be too hot and melt them and you'll have a big mess. i use my candy molds for saop and vice versa.have you tries mulk cartons? they come out cool.i like to put ice in them and then pour the wax. looks like swiss cheese!
if you feel adventurous one day try ithe a mold you dont care for and give it a go with proper precautions.
good luck with that .dont forget to look around the house for sturdy ideas on what else to use also.
