Kawasaki's opinion is NO, to avoid a rider from potentially overloading the bike. As a result some of the OEM racks, at least for the 1st Gen, are not compatable to have side and top racks together. Even these can be made to fit with minor mods.
However, like Thaylin says, there are many systems out there that work well together. I have Givi side case and top case racks on my '09. I put the top case on a year after the sides, and the 2 racks bolt together beautifully.
Always trust your cape.
