New RPG Game Idea

I have an awesome idea for a video game that everyone might love to play
First of all it will be an RPG, similar to Dark Souls, Bloodborne, and Elden Ring
So in this game the main character aka the player, can be customizable at the start of course, but what's different about this RPG, you can go to specific stations to change the character's hair style and facial hair.
The main character wears a long leather trench coat, wears a fedora, long boots, a shirt and jeans, he uses two main weapons. A rifle in his right hand and a staff in his left hand. He uses them both at the same time, and he uses his staff in many situations including fighting, puzzles, magic, etc.. With the rifle it's better with range attacks and extra firearm damage.
All his gear is upgradable and changeable. Like you can change his fedora, coat, boots, shirt, and jeans into different looks that you either buy or unlock throughout the gameplay. His weapons though are still rifles and staffs, but the rifle is upgradable and you can earn a new different rifle from specific shops. However the Staffs, you earn them after every boss fight, you earn a new staff with unique features and powers, that you can also upgrade, you can switch between you weapons if you want.
The style of this game should be like the 1800s but with mythical creatures such as Wendigos, Werewolves, Mutated Animals, Draugrs, and many many scary creatures.
There are boss fights such as giants, dragons, ogres, etc...
There will be a bunch of allies that will help and might have side quests
I think this game should be made by the same company of Bloodborne
so what do you think?
