Sona - Let's Add Some Complexity

Sona lost a lot of her hidden power the day her massive auras. That much I understand and appreciate - Sona could basically plant herself in a bush and invisibly pump her ADC full of power from a quarter of the way across the lane. Maybe fun for some old Sona players, but definitely not particularly interesting to play or play against.
Now her auras are small, but also a bit more powerful. She can still boost her team to great heights, so long as they cluster around her. It leads to some good team play (so long as the enemy isn't Malph/Jarvan/Ziggs or something equally horrifying to a grouped team), and may people seem to like it.
But many people, several of whom I play with on a regular basis, find it limited and far less interesting than her old, giant auras. I agree with them, but I don't agree that the old auras should make a comeback. Instead, I have an alternate solution. One that might raise the skill ceiling on Sona a touch, without hurting the base power or skill floor of what Sona currently has.
Sona is quite similar to Udyr in the way her skills work. She hits one for a short term effect, and then makes use of the persistent effect until she has need of a different short term one. It's a mechanic that works well for both champs, but I feel like Sona could do a lot more with that first press to fit into her theme. Specifically, I think her aura should pulse on cast.
Currently, there are little sonar waves that flow off of Sona to indicate her aura, slowly spinning around her as she moves. What if these had actual gameplay attached to them? Each different song can have a different series of waves in a different pattern, and when Sona switches from one song to another, the new effect fires out of her aura an additional number of units in a pattern dictated by the previous effect's aura pattern. This not only allows smart or aware Sonas to peg their allies with an aura from a distance if they line things up correctly, but it means the actual order of the songs played will affect exactly where and how she blasts the battlefield with buffs.
TL;DR: On casting a spell, Sona's Aura extends outward X extra units for a short time based on the pattern of her Aura at the time of casting. (See Image Below)
It's a small idea, and one I've probably used too many words to describe, but I feel like it would give Sonas a lot more tools - and more interesting tools - with which to feel powerful even when not right in the middle of her team, and not either right next to her ADC or slightly forward, poking with Q. Even better, it's a boost to her support functionality that doesn't throw her offensive capabilities way out of whack.
Any current Sona players like this idea, or am I way off base about why folks play (or played) her in the first place?
s riptide, this wouldn't really increase the skill so much as it would make Sona less able to make clutch plays, unless she was right next to an ally she wouldn't be able to shield them or speed boost them as fast, would be kind of a major nerf if that is what you meant.
