Almost certainly the paper will have significant fog, and higher tones may suffer a bit. Add some benzo or KBr (anti-fogging agents) to keep from coming out grey. Or, add a small volume of developer from a previous session to "season" the fresh paper developer.
The film will also show some slight fogging, resulting in slightly higher film speed. Look up Howard Bond articles in PhotoTechniques. Of course test the film beforehand with a textured target placed on Zone VII. Then look for texture.
