Well, I do not know where the CG is supposed to be on any paricular hover craft, but since you altered the center of lift you obviously will need to alter the center of gravity. On a given airplane design the center of lift, is somewhere in the vicinity of 25% aft of the leading edge of the wing. Once this is determined, the designer makes an educated guess at the range of where the center of gravity needs to be to make the airplane safe. Thru actual testing then the safe CG envelope is proven.

You are going to have to guess then experiment with your altered center of lift hovercraft. By using weight placed in various locations, you can using math, figure out what permanent components you can move around then to duplicate the temporary weights that produced the desired results.
