I like the idea but I don't know about reducing the time to 60 seconds.
Sometimes when I'm practicing by myself or with someone else in a public training room, someone interrupts by bombing either of us. Easiest way to deal with it is to just hog the bomb for 180 seconds and the troll gives up eventually.
If there was an option to have stop "it" and "bomb" from affecting you then I would be cool with reducing the time. Even if it was just a chat command like /noit or /nobomb or something.
