Quant shops seems to be the best path/least distance from old to new.
The only angle I can think is if you have mad skillz & passion for a domain and have done something interesting, like build an autonomous lawnmower or Alexa/IoT app for yr fridge to remind you to stock up. Slightly silly examples, but only a hook, such as publication in prestigious journal, will help you "beat" a PhD in the CV battle.
