Laptop panels do not usually have easily accessible way to get the panel provide HDMI support. Also getting
Also, you would have to figure out how to bring out all the GPIO connectors.
In short - it will look and feel like crap.

Mwah enough 12" or 15" hdmi monitors for sale and the gpio you can choose whatever you like, some scsi3 connector or whatever. Anyway if you really want it, it is possible.
Edit: tens of people already did it
ataradov:
This assumes access to 3D printer and other manufacturing capabilities.
I don't want a project. I want a tool, and I'm happy to pay for one if it existed.
Also that project does not really expose Ethernet or GPIO, since it is super inconvenient on the stock RPi.

To make a viable "kit" for most people to build, they would want to start off with a generic power supply/battery and charging circuit that would supply the necessary power to the RasPi and screen, and have the ability to view the status of charge (a small LCD showing percent charge, for example).
Then you could want an LCD screen that will take HDMI input, and ability to wire it into the power supply at the proper voltage. Finally, a USB keyboard with built-in trackpad would be needed to plug into the RasPi. Then a whole bunch of time trying to build a case for this hodge-podge that looks nice and doesn't fall apart, and then you can assemble the whole thing.
I found this 7" LCD with HDMI input board for $24 (Takes 12V I believe):

Then there is a USB touchpad keyboard for $25:

I think a big problem for many "amateurs" (even if they can hook up a screen and keyboard) will be getting a suitable portable power source that can supply a couple of different voltages (say for the screen and the RasPi) and handle all the charging and display info on the charging and battery level. And then stuffing it all into something that looks better than a briefcase:
:-DD

I don't know how well it would work to integrate into a laptop, but I have used those cheap LCD driver boards from China to repurpose various salvaged panels. Some of them are pretty small and they don't cost much so it might be worth a try.
Honestly though I'm not sure there's a big advantage over something like a Chromebook hacked to run proper Linux. The GPIO of a RPi is nice, but there are GPIO solutions you could use to interface external devices. Then again, the RPi does have a load of already worked out hacks and stuff that can be gotten working without a huge effort.
