If that happened I would expect the same success story as with Boeing-McDonnell Douglas merger.

Doubtful. The gpus are usually securely mounted and there is no chance for them to ram themselves into the ground at mach speed.

Why? That is an example of a bad engineering company being acquired and then poisoning the quality of the acquirer with its toxic, low-quality, corporate-politics-above-engineering culture.

There have been a lot of mergers where that has not happened.
