The onus is on you to demonstrate that it is better. A claim is not evidence.
You would also have to show that it didn't introduce another, possibly different, problem.
What about certification requirements? How do you know that the same or similar idea hasn't already been considered and found wanting? How many others have reviewed your idea/device to reduce bias or simple error/overlook?
Other factors such as cost & practicality also must be addressed.
I'm not trying to say that your concept isn't better. I'm trying to explain the types of things that your idea must get through before it would even start to be taken up.
It may well be that your perception of the problem is not one that bears up in reality. How many take-offs are there where there isn't a failure and, of those that had an EFATO, how many of those had no or minimal injuries? I don't know the answer but it has to be considered to properly address your concerns.
What is your idea?
