I have thought about the same, for the gyres, but I like not having any wires in the tank. You really don't see the wires for the gyres as they can sit so high in the tank, I figure I have about a week or so to change it. I do love the gyres and the way they move the water.
I think you would like it. I’m pretty sure you could add them and if you don’t use them they will be there if you ever need them... for anything... I turned the one in the back of my tank into the feed for my Uv sterilizer.. lol
