You really can't do it without coming to the US. In order to be issued a FAA commercial you must hold a FAA private (there is a way for military pilots to skip the private certificate.) As the holder of an ICAO license the FAA will issue you a private without a written or checkride. Your CAA has to verify your license to the FAA. There are two people in Europe who can issue you a private after this happens. To get the commercial and the IR you will have to pass the written tests for each one and they are only administered in the US. With the writtens passed you could train with FAA certificated flight instructors and the same two persons in Europe can do the checkride. To have the DC-9 type rating added (the FAA only issues one type rating for DC-9 from -10 to -90/B-717) you have to complete an approved part 142 training program and again there are none outside the US.
