If they were going to do that they'd have done it already.I know where you're coming from as everything have to be overly politically correct nowadays, but suggesting paralympics is a tad silly
What I can see happening though in a future series is the male and female categories being abolished, so to have all of the contenders and Glads bunched up together. This will be simply to pander to the gender police that makes up only 0.1% of the population. If you're a biological male (so bigger muscles, taller frame etc), then compete as a male. No 2-second head start for you on the Wall if you're a male but wanting to compete as a female. Knowing the BBC though...
As for knowing thr BBC. They didn't actually make and create or produce the show. They are just airing it. Produced by a third party production company.
