The problem is that sooner or later you will encounter a corner/wall/physical obstacle and the simple fact that boxers also train how to manage space and attack without over-extending.
Strong irimi seems like a more reasonable choice.
I tend to favor irimi and attack the throat. But that's me. A variety of responses are possible. But the desire to fight I think is a real problem and the ability to let that go is the greatest asset in Aikido.
