one should know what Aloe one is using. As we end up discussing frequently on the Cactus and Succulent forum: Only one Aloe is true Aloe vera, and while many other Aloes are known to have medicinal properties too, not all Aloes actually do. And unfortunately there are plenty of Aloes being sold at the BB stores and grocery stores labeled as Aloe Vera, that are not actually it, or people find an unlabeled Aloe and assume it is Aloe vera... and it is not. In all likelihood those Aloes will also have some beneficial effect, but that may not always be the case, and not all of them may have the same effects.
So before you start cutting up and scraping out leaves from your Aloe plants make sure you know what you have.
This is similar to collecting and eating wild mushrooms: make sure you know what it is you are ingesting as it is possible it might end up doing more harm than good.
I think this is a great Idea, but I would caution against using just any Aloe one can find.
