Anything can happen
This doesn’t play specifically into Dial of Destiny but overall it’s important to remember that Indy has seen and or experienced some very weird shit. Ghosts flying out of an ark. A man living without a heart. The revelation that immortality is a real thing. Oh, and proof that multiple dimensions exist and beings exist that can traverse them.
All of which is to say anything can happen in the world of Indiana Jones, no matter how crazy.
