This would not work as if you have trap cards you’d have to be able to select them to activate at the appropriate time. There is no way that you could play with one player not looking at the board at any given time.
If you set Man-eater Bug, and your opponent attacks into it, you have to be able to turn around and look at the screen and select the monster you want to destroy, which would have the hand revealed.
There is no way to code these interactions.
If either of you have an Android phone, you can download YGO Omega on android and play against your brother on the computer.
