ideas for books

i wanted to put a tenno or a warframe in the world of SAO, but every idea i had i scraped due to everything i wanted to do beeing doable with my uchiha in sword art online story

just so you guys know, the closest one to making the cut was baruuk, i wanted him to go full brawler who evaded atacks and disarmed oponents on sao arc, fairy arc and gungale arc, but other then the fighting style, i coulden't think of anything to change that i already have not planed for the uchiha fic, now sure, i could make mc's personality match baruuk as well, but i find it clashing hard with the world of SAO where you need to kill monsters to level up, that and i don't wanna go easy on SAO's human villans -_-
