I have my KR based in Los Alamos, NM, with a runway altitude of 7172'ASL. I use a high compression O-200 with the RAF-48/Diehl wings. I can't write a comparison to other KRs, but I have little doubt that my KR could operate out of Leadville successfully during the summer months. I used to have a C-85 on this same KR and believe it also would have been able to successfully fly out of Leadville. It's not unusual here on a summer day to have the Density Altitude of 10,000'. Leadville in the summer surely must reach a DA of 12,000'. Re other posts on this subject. At 7500', you get just a touch over 23" MP and roughly 75% power. If my O-200 really makes 100hp, that means it's roughly 75hp at this altitude. A KR will easily operate on that kind of HP, but the landing and takeoff speeds start getting fairly high. The rule of thumb is that you lose 1" MP per 100' and that is very close. I was showing 19" MP at 11,500' yesterday while doing some formation work with my KR and a new RV-9. I guess that what I'm saying is that with an O-200, Corvair, or turbo anything for a powerplant and the longer wing, I don't see a problem with operating out of Leadville. I would assume that the AS series wing would also be OK, but don't know how much performance testing has been done at altitude.
