Dynaudio seem to prefer 4.7uF capacitor into 8 ohms padded tweeter, 6.8uF would reduce power handling and increase distortion. They seem to use a bass Zobel with a bigger than expected capacitor value, perhaps to rolloff the midrange a little. For all that, First order crossovers aren't rocket science, so it's all quite doable, IMO. T trunkline

They are almost identical, except for R4, which is a 22R resistor which, I think, serves as a pad for the tweeter. The d28 in the A122C has an extra magnet for magnetic shielding, which also provides a little more output compared to it's brother.

The Contours are a more detailed speaker (D260 vs D28-2 tweeter) which you may or not prefer. The MKII also has quite a bit of a low end advantage over the A52 but if using a sub, that shouldn't be much of an issue. One last thing since you mentioned HT. The Audience center costs quite a bit less than the Contour which may be of consideration.

I used thicker cabinets walls, put multiple coats of borosilicate paint on the interior walls and substituted a pair of superior Morel MDT-33 tweeters for the Dynaudio D-260's. The crossover is the improved Murphy blaster crossover slightly tweaked to accomodate the different tweeters. The sound is incredible. So now here is the full story.
