Easy to say right now after Bummer has been terrible to start the year. I am probably one of the biggest Chris Paddack fans that isn't a PAdres or Twins fan, and I wouldn't do that deal.
You couldn't subtract Kimbrel, Bummer and Crochet from this bullpen the week before Opening Day just to add a SP that has half a UCL and is a ticking timebomb. Paddack has looked OK so far, but as teams see him multiple times the 2 pitch mix is going to hurt him. You also have the fact that if the UCL does eventually go, he's a non-tender.
Also Jace Fry is nothing like Aaron Bummer except for the side of their body they throw with.
