Idea: A competitive Tetris variant using a single grid

Consider a competitive Tetris variant using a single grid where the two players "drop" their tetrominoes in real time from opposite directions.

The color of the tetrominoes indicates which player sent them and the direction in which they will "fall."

When tetrominoes moving in opposite directions collide, they immediately stop.

Standard Tetris rules apply, including rotations and row elimination.

Has anyone tried this idea? Do you think it would be fun to play?
