I'd probably have tried that.

For filling, you can in a mode hook change the value of
fill-paragraph-function to something appropriate. The default is
message-fill-paragraph, which checks for headers as you can see.
I have no idea what other pieces of message-mode rely on the presence of
mail-header-separator though.
