Hey INRI,
You could try the Deluxe with the bright switch off. I know the midrange is scooped on Fender amps, but there are ways around that. You know, this is really unusual because more often than not, we try to get our ADA preamps to emulate our favorite vintage amps instead of the other way around.
Richard is absolutely correct about the chorus being set to 0% for the rate and the depth at 100%, I keep forgetting about that. Also he is correct about needing the stereo outputs of the chorus to get that big sound that the Crystal Clean voice has. Two amps would give a much larger sound than one, and if you go that route, I would use the Deluxe with the Vox. I'm not sure what controls you have with the AC15, but I think you can dial in midrange more on that amp than the Deluxe. If you wanted to use only one amp for this what I would try would be to plug both chorus outputs into each channel of the Deluxe, and use the bright switch on the Normal channel but leave the bright switch off on the Vibrato channel. This is because the Normal channel is noticeably warmer than the Vibrato channel to begin with, and adjust the treble and bass controls to get close. You can fine tune with your EQ pedal. Also, it's important to note that the volume on the Fender amps should be right around 3-4 and no higher as they begin to break up past that point. This is typical with all Fender BF and SF amps circuits. You'll have to experiment with the settings until your ears tell you this is what you're looking for.
As a further note, when it comes to chorus pedals, my choice will always be a pedal with stereo outputs. My two favorites these days are the TC Electronic SCF, and the Boss Dimension C. The Boss isn't as much a chorus effect as it is a stereo imaging effect, but it's cool. I may get the new WAZA version of the Dimension C because it has two inputs as well as outputs, which would be right after the chorus pedal.
I hope this is helpful.
