I like the idea. I think that makes sense. You could even do it on a switched jack. So that way it still works as the mono chorus, but when you plug into the dry jack the effect output is 100% wet.
I plan on doing almost the same with the Caesar. My plan right now is to grab one of these Buffer/Inverters. So I could do dry/wet out, and also the original and inverted signal for a wider stereo spread.
