ory – Is it possible to transit through Orly Airport with two separate tickets?

I’m Algerian and U.S. Permanent Resident, I have a repatriation flight booking from ORY to Algiers Airport and a Separate ticket from JFK to ORY passing through CASABLANCA Airport (Morrocco), I was wondering If I’ll be let to board in.
Thank you for your answers.
All flights are operated by Royal Air Morocoo, and Air Algerie from Orly to Algiers.
