It's a nice idea but Liverpool aren't winning the league, they'll slip up.
I think this will fail due to the rights, the current system is bidding on multiple packages (7) meaning you have pay multiple providers (Rip off) and they paid an eye watering 5.14 billion, so the only way this is going to succeed is if the rights holders want to invest in the technology themselves but as they are already paying so much will they do it? On top of that you can't show Saturday 3pm kick offs so it can't replace season tickets (this was put in place to protect the income from gate receipts of lower league clubs, they also do collective rights so you don't end up with a situation where the top 6 sell their own rights and take all the money). It might work in foreign countries though. I also don't know how useful it will be, if you're watching a match live you aren't really going to faffing about lining up different replay angles while the match is being played, you might at half time or after the match. As for 20 second delay people put up with anything up to that on streams so it's not a huge issue.
