Yes, the cowlings would not take much crumpling, but the engine casings and engine supports would probably take all the load as long as you didn't pile it in. You wouldn't be using the engine again though! There would be severe trauma on the engine supports, and the inboard flaps would not be happy. Fotr a -200, almost certainly 'beyond economical repair'. Actual wheels up landings on concrete can be remarkably bland, with just limited damage as long as both wheels are up and the roll out is straight ahead, not twisting. The trail of sparks must have been spectacular! I was abeam a tailstrike of an Eastern Airlines A300 once and it looked like a grenade explosion with a lot of sparks and smoke. It was startling, but the crew were completely unaware of it. They sounded rather hacked off when we told them!
