This will die pretty quickly. Half time is where the stadium vendors make their money and the Broadcasters can smash you with Adverts. No way this gets up.A 10 minute half time is bs, I can barely fit in a dart and a beer run as-is.
But I don't mind introducing a challenge system. Give each team one opportunity to challenge, it would cut down on the time it takes to review scores and would get rid of all the bs 'I touched it, no really I swear' time-wasting. If you lose your challenge then it's on you and not the umpires.
