This is really great news. We need certainly more options.
I have built a couple of workbench packs myself and it is a journey full of fun and trouble. It is really worth it.
I recommend that your first meditate on the philosophy behind it. What you want to achieve, and what will difference this wb pack/distro from others (appearance, hardware requirements, software choices, etc).
That is the key point.
Anyway, count on me with help or/and advice in whatever goals you choose.
Good luck and welcome to hell
