Here is some suggestions:
Key Eb LH/RH
Play chord octave higher:

/ F,G,Bb,Eb (2 octaves higher)
Play chord in ascending inversions:
Eb / F-G-Bb-Eb Bless the Lord
/ Bb-Eb-G, Eb-G-Bb, G-Bb-Eb, Bb-Eb-G, etc. (keep going up)
A little run:

/ Bb, Eb, F, Bb
A filler chord:

Eb, E /
F / A-C-Eb-G (filler)
