The low altitude drops were forced errors caused by the extraordinary (for the day) power of Seawolf missiles.
Plus all those bomb UXBs were on destroyers - unsurprisingly, as those were the perimeter ships. Britain could have lost many more DDs than it did, and still have won - the Carriers (and harriers) were the only critical assets, and they were never in serious danger.
In a repeat, Britain could still rely on the help of Chilean radar. It would also have the unsinkable aircraft carrier known as “The Falklands”.
I’m not so sure we could count on Chile. Relations between them and Argentina are much cosier these days.
