Crawfish Question for our southern Cooks

[salt and pepper]

Here in New York State, crawfish isn't ready available here. I never can get them.
My question is Would shrimp be a good replacement ? Any suggestions.
I saw Paula Deen make these and want to try them.

You can sub with shrimp. You should be able to trap craw fish in NY state. I get them in wallmart, check them out.
