Frankly, this should just be an enchantment.
Knockups are supposed to be fixed-duration stuns, more or less. Reducing their duration would negate the purpose of their existence (seeing that the only champion who actually uses the Airborne mechanic for their kit is Yasuo, who came out years after Knockup).
Then let's change all suppressions to knock-ups so no one's kit can be negated. kappa (Although imagining Malzahar's ult suspending the target in the air would be pretty cool...)
The point of suppression is what you claim knock-ups should be. Suppression is supposed to be the ultimate CC that renders the target completely incapacitated for the duration, meaning abilities, movement, summoner spells, and items should be disabled. All of this for the cost of "CCing" yourself, with exception to Skarner.
Honestly, I don't see why items and summoner spells can't be used during any displacement CC, but being completely suppressed allows such things like QSS to be used. It's just silly. I hope they do something about this for the next season.
Riot has experimented with knock-up tenacity in the past. Why they didn't go through with it, I dunno. I know it wasn't an animation issue. Knocked-up targets don't change when they are airborne, if you haven't noticed.
By the way, the knock-up on Janna's tornado (fully charged) is 1.25 seconds.
