That could work if you have done the soundings and found all the weaknesses. That takes specialized equipment though and you would have to insure that the additional cutting you did would not add any more weaknesses, and that is VERY hard to do.
What is even sadder is that there really is no value in squaring it up. It’s enough to just clean out the debris and then to tamp down the patch afterwards.
Every patch I ever did on my public streets lasted longer and was much smoother than anything ever done by the city crews. It really is not difficult if you put in just a bit of time and effort. And I didn’t find out how to do it via the Internet (I’m far from sure I could have found that info on the Internet when I first began patching holes in the road, but it is possible that info was findable a quarter century ago.)

I, openly, admit to being one of those folks who used to read while driving. It was rare, but I did do it. Zero accidents. And this was while driving in city traffic in the Metro Detroit area.
The corporate world of today bends over backwards to promote women and minorities over White men who demonstrably are more deserving.
