Getting my daughter into a power wheels

For those of you who don’t know, my 6 years old daughter Clara has dwarfism and is 1’5” tall at 18 pounds. I was thinking it would be really cool to get her a Power wheels car. Could it be modified though in order to use it ? I mean, this is going to be her power wheels, so it would be nice if we could make it where she was able to do everything from getting in it to “driving“ it around and being able to sit on the seat and reach everything while being tall enough to see over the windshield.

Also just to clarify I’m talking about those little kids power wheel cars that only go a couple of miles an hour
