Here are some more chord homonyms (chords with the same sound, but different 'meaning'):
Dom7(b9): You can place a fully dominant fingering one semi-tone above a root and you will get a rootless Dom7(b9). Remember dominants invert every four frets with the same fingering, so you can slide this chord around very easily.
Dom7(b9b5) aka Dom7(b9#11): Placing the fifth of a dominant fingering one semi-tone above a root will give you a rootless Dom7(b9b5). The other way to think of it is place a dominant fingering a tri-tone away from a root. This is the 'tri-tone substitution.'
Dom7(b9#5): Placing the flat-third of a min7b5 (half-diminished) chord one semi-tone above a root will give you a rootless Dom7(b9#5).
