I understand your theory about Avada Kedavra and Lily now. It has a few problems.
There’s no reason to believe that Avada Kedavra is that unusual. It is one of two advanced spells whose workings are explained in detail, and the other is the Patronus Charm, which also requires a special state of mind. From this, it is entirely plausible that emotion-based spells are common among advanced casters, and not a great rarity that a) has special unique features and b) no-one’s ever thought to study.
Your theory relies on all of our sources of information being incomplete or wrong (the entire wizarding world for all of its history, as well as Harry’s memory), which surely merits some kind of penalty.
“Lily had been experimenting on life extension.” Where do we know this from?
“In Harry’s memory of Godric’s Hollow, his mother Lily first gets the Dark Lord to agree to save Harry in exchange for her death.” I’m not sure how this ties in to your theory, but either way, I suggest you review her actual words.
“Not Harry, not Harry, please not Harry!”
“Not Harry! Please… have mercy… have mercy...”
“Not Harry, please no, take me, kill me instead!”
Unless Lily is an amazing actress, these are not the words of a woman trying to manipulate someone into completing a ritual.
In looking up quotes, I did find a line that strongly supports your theory, however. It’s when Fred and George are planning rumours to spread about the Defense Professor:
“...like when he claimed that you could only cast the Killing Curse using love, which made it pretty much useless.”
And this is Eliezer we’re talking about, and it also does so happen that if your theory is correct, Voldemort would have observed the results of Lily’s experiment and taken note of its success.
