How about something like this to protect everyone from turbulence:
Everything on the inside could be foam-padded to cushion a potential blow

When I looked at the title I thought it was going to be a different compartment entirely, like first class. One covered with specific noise-cancelling material to solve the problem of kids crying and being noisy in flights.
As a non-parent, I would prefer that option much more.
Also, the first photo you used isn't a good example. The bubbles would fall off across the plane when one of the wings would go up for a manoeuvre. While the swings would be a liability because the chains would be reactive to the axis change and gravity.
Small open slides seem like the way to go as the kids wouldn't bump their heads with sudden turbulence. Or make the upper part of the closed slide soft.
The spring riders would be a great fit for this, turbulence would make them even more fun for those brief seconds until the kids would be called back to the seats. :)
I also think that airlines could also look at hiring child party performers for 2 in 1 job as stewardesses, where they would sometimes have an act to entertain the kids for an hour or two during the flight. That would require just some soft padding for kids to sit on. That way at least those people would at least get to do what they like doing while also having the benefit of travelling and earning more money.
