Gaming laptop idea.

Reading a topic a user posted earlier of gaming laptop recommendations, I thought of a way for laptops to become more efficient for mobile gamers.
Mobile gamers cannot swap out laptop GPUs due to the reason of laptop size and other few factors, but think I may have thought of a solution to make mobile gamers happier.

There is no such thing as the perfect Gaming Laptop in my opinion, but there is a concept I thought of that might improve it. Instead of relying on an external Thunderbolt/USB 3.0-based GPU, why not just make a GPU that can become external.

My concept includes this:

Image 1:
The basic laptop layout internally, because of the large amount of components and the size of components inside a small space, the air cannot flow very freely, the GPU fan not having a good amount of cold and freash air reaching it (the red arrows show the air flow inside).

Image 2:
When the GPU reaches a certain temperature (for example, 60C (about 120F)) the GPU on a protective mount and sleeve comes out of the laptop case to get air to the GPU fan and effectively cool the GPU (or you can put the setting to manual so you can decide whether it comes out or not). The GPU coming out of the laptop would also produce better airflow and cooling to all of the other components inside too.
And another thing I thought of is instead of using the normal fan, use one that pulls air in from the side and pulls it to the center to cool off the Graphics Processor Core (an example of this method is the concept of "The fanless spinning heatsink" design, there would be a hole above the core for the vortex to form, eliminating dangerous spinning fans atop the GPU when is comes out of the case during operations.

Upgrades?
When the laptop is powered off you can pull the GPU out and but a new one in, like you would do with any gaming desktop, this being possible if manufactures can make a special kind of GPU for laptops, along with laptop manufactures putting the same design layout so the GPUs can fit, along with aftermarket laptop power units to provide power to the different finds of voltage standards for the different GPUs.

Tell me what you all think of my concept and provide feedback on what problems you think would occur.

All you need is money!

Yes, I have, but my idea is not only for upgrading and replacing, but also introducing better cooling of the laptop components.
