Eli5 why no big Insects?

Okay so I’m sure if you’ve read in history that sometime around Jurassic age that insects were like stupidly big due to O2 saturated environments. why can’t we manufacture an enclosed space with gradually increasing oxygen saturation over a few generations and see how big we can get insects?

Sorry for format using phone

Evolution isn’t a short process and size is determined by genetics moreso than environment. It would (and did) take millions of years for insects to evolve to new size. You might see some slightly larger variants after a couple of thousand of generstions, but only by a centimeter or two.
