I'm not sure a video game would work well. There was an American Gladiators one in 1991 (before the UK show started, so it kept the US branding even in the UK), and well, it's generally regarded as poor. There's never been another attempt since.

I'm not advocating for it, I wouldn't buy it and I don't think it'd neccessarily be good. I'm not even commenting on likelihood. That's quite different to ackowledging it's possible though, while still being a BBC hit programme.

It's certainly more suitable for adapting to create a video game from than, say, Little Britain - but that happened.
