Stuffy the USN would be ok they are purchasing F18E/F/G to replace some the more clapped out airframes so could extend their buy
The USMC and USAF would be a bit more stuffed as the F35 is more tied to their concept of operations and they are replacing several types of airframes with the JSF and cutting manpower by going single seat (I don't know if weapon officers would be phased out or if they will just 'get' a JSF as it were as I guess the retraining burden for BFM and all the other stuff would be fairly costly).
