I don't get it. People already lose their minds over something like Royal Menagerie, and you want them to be able to access this fight... for what exactly?
The devs already made this savage tier a tad more simple (I haven't beaten any floor mind, just going on what I've read and what videos I've watched) so that it is more accessible to people who have neither time nor patience to dedicate weeks into clearing overly difficult fights - this is supposed to be a kind of reward and a mini-game to the people who clear all floors and are looking toward something a tad more challenging.
Give it a few month's time and you'll be able to clear the fight with echo - I really don't see the point of adding a "normal" version of a fight that is supposed to exist solely as the HARDEST fight in the game, and I really am not looking forward to another trial that everyone cries about because being normal or story mode implies everyone should be able to do it blindfolded.
