Ouch! No, it wont work in a short time like that...it needs time for the cure to do it's magic. And, if there's salt in the marinade (I'm sure there will be with it intended for cure), osmosis will already have occurred, and the cure won't penetrate the meat nearly as well, even if given a couple of days. If you increase the salt in the marinade by 50% or so when you add the cure could work, but you may have to soak it in fresh water for a few minutes to draw out some salt before smoking & drying.
Not to pry the recipe from your tight gripped fingers, but how much liquids and salt is in the marinade, say, per pound of meat? If it doesn't have a lot of worsty or soy sauce and other sodium containing products like ketchup, you may be able to get it cured without adding excessive amounts of salt.
You may need to get this figured out, cure added and just wait for next weekend, or your next available day to smoke and dry. It won't hurt anything to cure for extra time, but too little time or too little cure can be the game-breaker.
