Did you consider using periodic calls to keep the Lambda@Edge functions "warm"? I've been playing with Zappa (https://www.zappa.io) for standard Lambda and it sets this up by default.

Yes, but it's kind of a whack-a-mole since their reuse times are not public AFAIK, so it would constantly need tuning as they develop the service.
