No, it's image question. Stuff that goes into an image is an image 
question. I have multiple devices without a screen and use angstrom on 
it without troubles. There's absolutely no need for yet another distro.

Create tasks and images for it. There's absolutely no need for yet 
another distro.

Have a look at meta-sdk*.bb, that shows how you can install packages 
into a toolchain.
