an idea i found but the author deleted it was a crossover between Jojo part 6 and mha but was deleted sadly, where izuku helps out in church but is also bullied for being quirkless, he asks for a miracle from god and is given the stand white snake( whitesnake can turn people's quirks and memories into disks and insert them into his head for the quirk) and is given the task to acheive heaven by speeding the universe up to infinity by first collecting the souls of 36 sinners. along the way he saves eri( after defeating overhaul) and meets uraraka at the church to pray or smth, last part said he was going to check out UA
the original story was called the road to heaven, it may still work for you. it would also help to watch part 6 of joJo for more info on heaven's plan
