One way to make the chord progression more like Bach is to use more complex chords and add in inversions. Here is a modified version of the progression that incorporates these elements:
G6/F#7#9 D7#9/F# F6/E7#9 Eb6/D7#9 Cmaj7/G Gsus2/B Cmaj7/G Gsus2 Fmaj7/C Csus2/E Fmaj7/C Csus2/E
I added in some inversions and substituted some of the chords with more complex voicings. This gives the progression a more rich and ornate sound, which is characteristic of Bach's music.
