I like your thinking outside of the box. The format is what it is today because of people who think creatively, but you need to think of something your tog deck does that the existing proven archetype does not, and start form there.
GAT has one of the best engines in the format right now. Playing one card gives Tog +6/+6, or does something equally ridiculous, like draw two cards and gain 2 mana for 2 life. I've seen GAT go gush crazy and time walk, to swing for lethal effectively turn 1. How does playing

, creating a temporary answer to my win conduction, and waiting a turn to play an

cost creature improve upon Existing GAT or Oath decks? Frankly, it seems a lot easier just to tap the extra land.
Additional example: why oath out tog which has the risk of coming into play off a shallow oath activation and has problems beating through aggro, when you can oath out aroma/razia combo and easily fight through opposing aggro for roughly a 2 swing haste kill, or tyrant, which has the ability to cripple your opponents board and also has few problems with opposing aggro.
The two deck types you’re merging together just don't seem to benefit form the merger. It’s great that you’re thinking about new decks. But it seems you’ve started in the wrong place. Instead of starting with “this is a
different way to kill”, think of “this is a
better way to kill”. Granted there are more dimensions than kill, things like disruption and consistency, but that seems to be where you’re going with this.
I know this post seems a little harsh, but I hope you found in insightful, if we all teach each other as much as we can, we're going to have a lot more interesting games,and be much better players.
