Might be an improvement. Flying schools are very capital-intensive, so possibly a large operation would be more efficient and able to acquire and utilise a bigger and better fleet of planes.
You'd also hope that the bigger operation would facilitate the development of a better curriculum.
Another possibility is that t would create a better known, almost universal, brand that would be appreciated by airlines.
Existing smaller flying schools are largely niche players anyone and I suspect this would continue.
One thing that impressed me about Oxford, after GFS, was the ability to move staff and planes between continents as required. Seems sensible to me, and the opportunity for young instructors to work overseas is a great idea.
