It would still take more space on the page to represent the same amount of music which is also important.

Many people have tried to replace standard notation, over several hundred years, and no one has yet come up with a compelling alternative. So it's probably a very difficult task. Systems that are evolved over a long time, like musical notation, are often far more robust than those that are designed from scratch.

If you're really serious about proposing an alternative I would probably start by considering why other competing systems have failed.
