It will be flagged as a defect if inspected by IPC-610 (Classe 1,2 ou 3). So what you’re trying to do is not acceptable. Damage to one of the pads (top or bottom) is also a defect.
I have seen boards where the pad is not a perfect circle (like an ellipse) to make space for traces to go in between. This seems acceptable.

How does a conventional board house deal with the issue of reflow during PCB component assembly with BGA’s on both sides of the board?
Are two different solders used (like regular lead free SAC305 and a low temp?)
I did have one board come back with a manufacturer error – an extra bit of copper just a hair’s width across hidden underneath a component. It looked almost like someone’s eyelash had fallen onto the board just before photo etch. How should I deal with it?
I am a buyer in a telecom company. Recentemente, an important order of SMT PCBA is delayed due to insophiscated production of a supplier. I am thinking about replace it and just very puzzled about how did their SMT pad fall off easily when soldering the PCB boards. That slows down the whole process.
