You can not import them, but you could use Narrowcast Server to deliver them! Of course, they would be static reports at this point, but I am sure that would work.
Here, we are using it to deliver our "old" Focus report while we are building/expanding our current MicroStrategy project. From the user point of view, this is much better, they only go to one interface to get all their reports and we bought us time to build the project right (as opposed to "too fast"...).
