That's kind of how it already works, and it's not really industry specific to guitars.
Small shops innovate, as they're much more agile (typically) and due to market factors they need to innovate to stay above water.
When they hit on a great idea the larger manufacturers come in and use their supply chain muscle to make said innovation cheaper and faster to implement, which makes it more available to more buyers.
So the little guy is better at new ideas and the big guy is better at making them happen.
Yeah. This is going off topic, but look at companies like Thermo Fischer. That company is basically only a sum of its acquisitions! There's like 200 companies they own, and really have no R&D of their own these days. They are very proficient in scouting new companies and regularly buy new startups and younger companies' innovations to their product portfolio. It's really effective and probably the wisest way to operate such a company.
Guitars work differently, but it only makes sense that exactly what you described is happening
Talking about innovation, I wonder if some bigger company comes up with a mass-produced, cheaper version of a resin-guitar like Aristides, and in more traditional shapes (than Aristides). That could be something. Imagine a Jackson Soloist or an ESP Horizon that resonates like hell and sustains forever!
