Now that would make a great fanfic!

(too bad Pulaski and the EMH aren't part of the same ST franchise; it would make it much easier to search on FFN to see if anyone's already written any stories about them)

There's a comic, Flesh and Stone, that features both of them, along the other pre-DSC Trek doctors.
