Fairly sure there aren't any direct rhymes like that.
Closest would probably be 'humour'/'humor', or 'fervour'/'fervor' (which could mean happiness, or any intense emotional state).
Could also try 'amor', 'adore', 'evermore'.
Hope one of those vaguely helps.
"Glow" can be a rhyming word for "fellow" and it can also mean happy or delighted.

The word "voracious" rhymes with "vivacious" and means having a strong desire or appetite. An alternative word that means happy or joyful is "delirious."
