In that case, these are the few things I can suggest:
1) Add a passing chord or two, it will add a new dimension to the progression.
2) arpegiate the chords, U'll be amazed how powerful they are!
3) If you will arpegiate, then it's well worth adding power chords on the LH or adding other rootless voicings on the LH..
I'll try to play around with them & see what I come up with & post it.
Thanx for sharing MrAndrew--You are really talented.
