Does anyone here really think this isn't months of work? Maybe in 1942 this would have been an engine change and back up for tomorrow night's raid. Not today, I'm afraid. The damage assessment alone is going to be a long job.
There are so many parts at risk there, parts that no longer sit on shelves. I pray they can be sourced/manufactured in reasonably short order, but what I'm saying here is don't hold your breath.
She'll be back.
