I have a pretty good idea of how to boost her viability at coordinated levels without causing major issues in solo-Q:

Whenever an ally hits an enemy champion with the bonus proc of Hymn of Valor the cooldown of her ultimate is reduced by X seconds.

So if the reduction was 3 seconds then absolute best case scenario would be 12 seconds off her ult every time she cast Q, Sona not being capable of proc'ing this effect herself.
