I know it is hard to keep up with the language, but for the future, "differently abled" is usually considered to be a bit condescending. In this context, "people with disabilities" (which puts the focus on the fact that they are people) would usually be preferred.
I cannot speak for anyone else. My brother used a wheelchair his entire life. We had many times we'd talk about things like this. He would have found this, okay, but... lacking.
His best example of his position was the Marvel superhero Daredevil, and considering him to be representation of people who are blind. They manage to do that by giving the blind man the superpower, "Can see better than everyone." That's... not really blind, now is it?
This allows for representation by eliding over all the difficulties. Real wheelchairs are not lightweight, easily maneuverable, not really in the way, allowing you to go over any surface and up and down stairs with ease. While these days you can get a bargain basement chair for reasonable cost, sports wheelchairs are in the thousands of dollars, often a stretch in the budget for a family that is also paying whatever extra medical costs the user has (which are usually substantial).
My brother was not looking for people to think he could easily do anything they could. Because he couldn't. He wanted people to understand that, be a bit more thoughtful in their choices, and treat him like he was a whole human being regardless.
