>>> If the imported chords are placed in a new "song", wouldn't you be able to simply choose a style, and then play it?

Yes. The purpose of being able to import tracks, is to allow you to import the melody (or counter-melody) of the MIDI file, which wouldn't be part of the style.
But you can, for example, read in a MIDI file, have it interpret the chords, then choose a RealStyle (in a similar style), and have Real instruments playing in a style similar to your MIDI file.

Have Fun!
