I'm assuming solo play: Playing infinitely in Tetris means repeating a pattern over and over again. I would suspect that transforming Tetris so that it is universally infinitely playable (probably by somehow erasing the fact that an infinite SZSZ is a death sequence) would lead to a game where the optimal play is also to repeat a pattern over and over game. It would be indeed a game of skill but would rob the player out of all creativity and agency. Not a very fun game at the end. But I think that proving that such game is infinitely playable is a hard (np hard ?) problem.
