By the time either a blimp or this thing deflates enough to make the engines flop around, there isn't going to be nearly enough lift of lift of any kind to keep it in the air.
But let's ignore that: You want to do this to a rigid airship.
Look at their history. Excluding the ones that burst into flames, many if not most of the major airships ever built ended up lost due to failure of their internal structures. They got shredded like pretzels with the slightest adverse aerodynamic forces. (Even the Hindenburg disaster probably initially involved the snapping of an internal bracing wire due to overzealous steering.)
If I had to ride in one of these white elephants, I'd still go with the inflatable version.
