Does microevolution logically include macroevolution?

New stuff on lion/tiger and cat-in-general divergences is hot off the press in Science 6 January 2006: Vol. 311. no. 5757, pp. 73 - 77. They have lions and tigers splitting about 3.7 million years ago, based on genetic markers of several sorts. So your "100 times longer" may be a bit of an underestimation. The paper is about the entire Family Felidae, which originated about 11 million years ago by their estimate. It would be most interesting to see about some other possible crosses in that family: I'd never heard of a kodkod, but I'll bet a kodkod X ocelot would be mighty purty!
