This creates a fascinating transformation.

Instead of swing:

slow 4/4 neo-soul.

Keep recognizable melody.

Use:

rich 9th/13th voicings

laid-back chord entries

bass anticipation

minor-IV color

chromatic slides.

The tune suddenly becomes almost unrecognizable stylistically while still melodically obvious.

That is precisely the kind of independence we wanted from the song lab.
