You don't have to have 20 repos. You can place the modules into a single
repo with subdirs.

The bitbake documentation claims you can specify a directory in the 
file: fetcher, and then all of it will be unpacked to workdir. I've 
never seen or tried it myself, but maybe you can investigate in that 
direction, and make it work if it doesn't.
