CG calculating will be fun with 2 centers of lift. I was thinking about doing something kind of arbitrary like this. Calculate CL of each wing. Then get the wing area of each. Say the front wing is 100cm2 and the rear is 150cm2. So then add them up, and the front wing is 100/250, and the rear is 150/250. So the front wing would be providing 40 percent of the lift, and the rear 60. So then if there is 20cm between the wings, the cg would be about 12cm back from the front wing and 8cm forward from the rear. It would be simple but it seems like it would work. I realize there are tons of outliers and variables that could happen, but be close. I think that would work, logic is solid. I think I read somewhere that the front wing provides 60% of the lift. I will try it and see how it compares, thanks. I just made that up based on my own logic. There may be some aerodynamic reason the front wing provides more lift too.
