Maybe but I would say that changing the size to E and SPACE to jump, noone would say a thing. In Celeste, it took me a very long time to learn that C is for jump, even tho it is objectively much better for a precision platformer like Celeste is. If you are making a small game that the player is going to spend max a few minutes on, you should adapt to the player and not make the player adapt to your game like you would in bigger games :D
