I ended up contacting the folks over at RacingBrake about their c63 rotors and in that process explained what was going on. Their engineering department got in contact with me and they explained that they would be able to manufacture a hat/rotor combo that would guarantee fitment with the floating calipers on our cars! Huge ups to the folks over at RB for taking the time to look into this, hard to come by that level of customer service these days.
With the caliper reinstalled, tons of clearance between the retaining/squeak spring and the hat.

Wheels back on, seated pads
Using centric posi-quiet ceramic pads again. Also installed new "ornamental" plates and retaining/squeek springs while I was at it. Had a hard-ish time finding the part numbers so:
2000 c230 kompressor special edition, 2012 E550 coupe (sold), 2017 C63 sedan (sold), 2018 C63S Coupe

Thanks, they feel great. Just as smooth as stock rotors (when they're not warped of course...) I've not done anything objective...so no proof other than (inverse?) butt dyno, but it feels like they've got a little more initial bite and that I have to apply a little less pressure to achieve similar braking power to stock. I've surprised myself when giving the brakes a little tap to turn off cruise control. I'd assume due to the lower rotating mass? Or maybe its just my mind trying justifying the cost...haha
