"The issue is that all champions who can't poke tend to suffer in ARAM, so the game mode probably needs more effects on its aura to make engage champions work."

The aura kind of falls into what you say later...

"Generally, fixing a dysfunctional game component by adding an "optional" extra effect doesn't work at all, and makes the issue more complicated to properly solve later on."

Simply put, the aura as it is does little to nothing. The mana regen doesn't bump mana-starved champion's chances of winning and still reigns supreme despite the heal debuff (and  only descended from the Top 5 because of her rework and / abusing her new fragile early game). Even if something was added in the aura to help engage champions, I don't think it'd be enough to make a dent in the ARAM meta.

The only thing / did was denounce which champions need a proper engage but lack it (,, , among a few others) and which champions don't need a second tool for engage because they either become frustrating (, to name a couple}} or stupidly suicidal (oh boy, the amount of  players getting cheeky with it and getting CC'd to death). That's why I wouldn't really miss the spell if it was gone tomorrow; sure it's fun, but at the end of the day it's just a bandaid to a bigger issue.

I'd wager that, spell-wise, both ARAM-exclusive spells need to go and have the good ol' active back as a spell to tone down Teemo and pokers from the brushes. As for the deficiencies that those spells serve as bandaid, Riot needs to get its act together and seriously tweak all champions in ARAM (resource costs, amount of damage, movement speed, even the range of abilities shouldn't be immune to this... and give a spell to E that actually works for something other than pretty lights). That's the only way poke will lose its hegemony and engage champions can finally have a decent shot.
