Yes. Basically the only difference between different types of sugars (dextrose, sucrose, fructose, etc) is either the shape or the number of carbons and in some cases whether they form chains. Some are absorbed directly and others are broken down into the simplest form which is most useful for our bodies to absorb: glucose aka dextrose. So using dextrose rather than sucrose does nothing.

Good luck with candy saturdays. It sounds like a good concept!
