Yes, I would love to see them. Here's an excerpt from a blog of mine.
Look at the rings from the OoX. These things offered customization and provided specific benefits depending on which ones were equipped. They had features like dealing more plus taking less damage, automatically recovering hearts, no sliding on ice, and even turning into a specific enemy. The only downside was only one ring could be equipped at a time. What if this were improved by working more like the medals in Skyward Sword where them being equipped takes up a slot in the Adventure Pouch, allowing for multiple rings -- or whatever kind of item is used -- to be equipped at once? Or maybe they could have their own container like they did in the OoX (the Ring Box), only have something like a point amount assigned to them with a maximum number of points available for use. It would provide a lot more resource management and would allow Link to have lots of cool enhancements, which would be perfect for Zelda.
Then you have the upgrading mechanic featured in Skyward Sword. Treasure and bugs obtained either in the overworld or via an enemy drop could be used to upgrade Link's items and potions. Certain quest items could be upgraded to receive specific benefits, while extra containers could be upgraded to hold more of their respective items (Bombs, Arrows, Deku Seeds). It's a cool feature, right? Well what if it were to be enhanced in the future? What if there were multiple paths for upgrading items? What if we could upgrade Link himself? Gain specific skills to use, such as the aforementioned Hidden Skills and Tiger Scrolls, only flesh them out a bit more. Or maybe having the ability to pick up enemy weapons come back, only with the ability to store them in a pouch. The list goes on and on.
Magic could also fall under this category. I actually don't think that magic is an absolute necessity for Zelda, but when executed properly, there's no doubt it can only be beneficiary. In fact, if it were to be merged (properly) with the more mechanical side Zelda has seen ever since The Minish Cap, that would be pure gold. If magic were to be brought back, though, spells should be a part of the mix. There isn't anything wrong with the use of magical items, but they alone just don't do the use of magic justice. Physical use of magic, like that of Zelda II and Majora's Mask, should be a part of the formula if magic is ever to be at is maximum usefulness in Zelda. Of course, this could also use something like purchasing more powerful magic abilities. Or perhaps a skill tree -- earn skill points from killing enemies and use them to power Link's magic abilities up. The possibilities of what could be done are enthralling to think about.
