I have started putting it together to do a little testing (and look over skills/spells in general).

Currently it is called the Polymath guild (google the name) and I am putting in only skills/spells level 9 or less.

Will do some testing to see how it works out. Basically i think it would be fun and cool to start, but then later you'll miss out on the advnaced power of a dedicated guild, but might be a nice way to get a feel for things.
