Have you/your parents considered therapeutic riding lessons for your sister? That might be a better way to start out before actually buying a horse. I mean, I trust you know that she should never be on a horse without assistance. A saddle isn't going to keep her on the horse, she would need side walkers at all times.
I wouldn't recommend a draft horse unless you're thinking of a smaller breed (Haflingers, Gypsies, Fjords). It would be much easier to hold on to her on a shorter horse. (And just a little side note, Gypsies can be very pricey, just so you know). There are also plenty of non-draft horses out there that would be suitable for a disabled rider and first-time horse owner. It really just depends on the individual horse. I would recommend having an experienced horse person with you when you go to look at horses, as well. Their opinions and knowledge are invaluable.
