Well to each his/her own but that is really a difficult path. After all that training it is pretty unlikely that you would find a position where you are combining em/im/im subspecialist. Most likely you will end up practicing in just one of those areas. It sure would be nice to try to decide what you want to do beforehand and skip all of those extraneous years of training.
IM/EM/CC has been mentioned at length other places on this board; it apparently is not pretty unlikely to find places where you do EM one block, IM/floor/hospitalist another, and/or ICU/MICU another block. There are people in Detroit, Pittsburgh, and New York City doing it.
Beyond critical care, IM/EM/Tox is another power hitter - especially in this day and age, you can almost write your own ticket in the bioterrorism market.
One I haven't heard of is IM/EM/Cards - but, at 8 years, it's on par with CT surgery, and there is at least one program (UVa) that has an EM/Emergency Cardiovascular fellowship.
Other IM fellowships would be of ostensibly lesser utility to the IM/EM grad.
