Does Riot ever plan on lifting permabans for players that show genuine signs of reform?

I was reading more into the history of this game (as I do when I'm always bored) and I stumbled across something called the "Level 20 Challenge" where players that showed the best signs of reform were given one last chance and it was such a horrible fail that the project was scrapped entirely.

Now, I'm not permanently banned myself, but as a general question of curiosity I'm asking - **Does Riot ever plan on giving permabanned players one last chance to reform? **

If I had to choose it would be difficult, but I would probably say yes because I'm sympathetic towards players that are not just blatantly toxic (counter toxic, not severely toxic to their team - players that use racism, homophobic slurs, these are scum of the Earth that don't deserve a second chance) and for one other reason. I believe the very experience of being permabanned is enough for one to truly reform because it lets them experience what will happen if they don't, for example we can say we all despise cancer and never want to be diagnosed with it but can we "really" know what it feels like to have it unless we actually experience it for ourself to understand the feeling? It's actually the same with being permabanned, none of us want to be permabanned but in reality why is that? Because we don't want to lose our accounts? The thing is we have no idea what it actually feels to have all that hard earned money and time taken from you until is finally to late and your account is banned, terminated, etc.

Also I believe toxic players (not severely toxic, people that for example say they wished you died in 9/11 - a player has said this to me before) are not the scourge of this game but intentional feeders and hackers are - this right here is what breeds toxicity and triggers the natural human response of anger and frustration because it's directly hindering the goal that every player has which is winning.

Anyway this was mainly just to start a discussion as I'm bored, feel free to share your opinions.
