This might be a bit confusing, the Zone is a bit of a difficult thing to explains since its psychology
I would say there are three things required:
Skill - (This is why Kuroko can't go in the Zone - he is not skilled enough at the game and thus thinks too much about his actions)
Mental Focus - (This was the issue when Kagami couldnt go in the Zone against Yosen)
Willpower to push yourself - (For Kagami this is the need to not let his teammates down, for Aomine its the competetive spirit of beating the guy in front of him and so on)
The love of the game for example doesnt truly come into it - you dont need to love it if you take it compeltely seriously, its part of the Willpower. So assuming Akashi can max out these three conditions, he too can go into the Zone (though honestly the whole idea of Zone being something you can "choose" to not go into or the time limit on it are a bit of a magical BS. As someone who tends to go in the Zone quite often during competitions - its not something you induce actively - it can even be really annyoing since you go in the zone and next you know it the event is over and a blur in your head)
