First of all, welcome to the site. Sure it sounds workable assuming the hive is full of bees. It would be a great way lessen the chances of casting swarms, increase your hives, and learn a little easier. Smaller hives are easier to work though a split can turn into a full size hive very quickly. By that time you'll be feeling a little more confident.
You'll be a whole lot smarter with what you've got when you open up the hives though.
