Eb, A, C, G, Bb, E

Now you can't use your little mode boxes, bwahahaha!

Seriously, though, this forces you to stop using boxes and to listen to what you're playing. Solo in some weird tuning over jam tracks for like a week. When you start to figure out finger patterns, switch tunings. You have to use your ears to judge what you play, and therefore your soloing will be melodic, rather than theoretical. You'll hit a lot of sour notes at first, but when you do this for a while and then tune back normally you'll be using your ears more.
