I have a mountain Tandem that is fitted with Hope Mono M4 discs and 200 mm rotors. This brake system works. Although I may be tempted to go down to a 180mm rear disc- There is no way I would fit 6" discs on the thing. Even with one of the best Tandem Disc brake units around- I do not think that a 6" rotor will be able to stop our tandem at full chat- let alone a Road bike that will be able to travel a lot faster. And as to the quick release axle with disc brakes- I tried it for a couple of weeks when I converted to discs- and for peace of mind- if not for safety- I changed to a bolt through axle. The angles that fork was going through with the strain of the disc brakes had me worried that the QR would break or come loose, if the rotor did not pull the qr out of the forks.
Admitedly this is an offroad tandem that takes a lot of strain with the terrain but CF forks- 6" disc- and no bolt through axle would make me think seriously about my safety. Even on the road.
