Yes, there is a reason. Midi only knows 16 channels and also one port.

If you have 4 midi files, each with 16 channels and each to another port (one for linuxsampler, one for fluidsynth, one for zynaddsubfy and one for aelous) you can't mix the midi anymore.
If there was a super-midi (jackmidi .jmid :) ?) format with unlimited channels and several ports per file and a player for that format you could think about mixing it before hand.

But if such a format would exist I would export directly to it instead of standard midi anyway.
