This means a fairly small group of chords. Not sure it covers more than one key.

Once you can move a 5th you can move anywhere because it's a move of 7 in the integers modulo 12 (numbering all the notes chromatically) which will get you back round to 0 in 12 moves. Maj -> Min is only one note change, as is moving inversions or adding or removing a 4th note.
