Agreed with Cirrus. I can see what you are trying to do, but I personally think you have the wrong cards for it.
I use to play a lot of different HERO decks, so I like to think I know a bit about them! :3
I think you should scrap the Polymerization for Fusion Gate, as it is much more broken in HERO's. You could play Gate HEROs with a water twist, then you can keep your Mask Changes and abuse Ab Zero and Acid, because Ab Zero is so broken.
