I only have the original, both in cabin as well as check-in size. The cabin one has been checked a couple of times when the plane ran out of space. All handles work perfectly fine. The cabin one is 9 years old I think and the check-in almost 5 years.
And I love your idea (I don’t have kids though yet, so can’t comment if there are any downsides).
