And Maj 9 is possible of course...

What would also be good is if BIAB actually played supported chords as written.
Extended dominants like 7b9#11b13 are theoretically possible but in practice only really played by dropping one or other of the extensions. What you miss there is not so much functional as colouristic..the extra tension sound of more than one semitone in a chord occurring simultaneously.
