How would I, an able bodied person, be able to respectfully cosplay a character with a disability?

I would really like to create a cosplay of the character Charles Xavier from the X Men movies, however it's a pretty well known fact he's a wheelchair user.

I myself don't use a wheelchair, but I want to do it in the most respectful way possible and I thought it would be best to ask disabled people their thoughts.

I wouldn't want to omit the wheelchair and remove the disability, because especially within the franchise I understand the representation is so important (the Xmen are a superhero team made of 'mutants' who face a lot of discrimination)

However, I don't know if it would be ok for me to use a wheelchair for costume purposes if I don't use one - I was thinking along the lines of when people say my culture is not your costume.

I just wanted to see what people thought and how to potentially go about it, if at all. And I honestly don't mind if people tell me not to either.
