Would it be reasonably complicated and/or meaningful, to get ecj to evolve
some sub-set of the ecj settings?

I'm working on a project, where I'd like to determine what effects different
settings have on the outcome. Settings such as population sizes,
mutation frequencies, migration and such. Instead of manually setting up a
thousand runs with different settings, I'm wondering if ECJ could
be tasked with handling this?

The fitness for the meta-ecj could be calculated from for example the
average time it takes the "normal" ecj to reach a certain fitness level.

The main question in my mind right now is how one would express a
settings-file in a evolvable fashion.

Any comments, pratical or theoretical, would be interesting.
