I can see no reason to even attempt what you're proposing. The PIC can perform any function the 555 can do, without any external components. And do a bunch of other stuff at the same time.

It would be like using a 300hp car engine just to regulate how fast your electric can opener turns. Not that someone wouldn't try that either.

I have seen people using 12C508 direct drop in 555 place upside down (different supply pins ).

Compared to 555, 12C508 provides a better accuracy over a range of frequency they say. Thus, it comes to the cost at the end.

555 is about the same price of a single general purpose transistor!
