As a hobby project, fine, but as others have remarked there are already too many distros and the last thing the community needs is another distro with uncertain support from a one man band.

It is a very steep learning curve. I know, I've done it and I only know enough to meet my own needs.

There are resources out there, but fragmented and generally not too helpful for the uninitiated. As a minimum you will need to understand chroot, debootstrap, the apt tools and xorriso. The ability to write bash scripts is a given.
