Changing Dates on Letters Myself

2 of my 3 letters are from a therapist and psych I no longer see. They're from 2022 and I got the impression I need newer ones.

Would it be a really bad decision to just fix the dates by editing the PDF's? I mean would it even get back to the doctors? Cuz it just goes to the insurance, right?

Don't wanna get in legal trouble, but it's a pain in the ass to get two new doctors when I already have letters.
