2d curves and a 3d plot on the same plane

Hi, I am a newbie to desmos.
I want to create two normal distributions by giving certain values (mean, standard deviation, population size). Then, using the output values (the two distributions) build another 3d plot. Would that be possible to do it on the same plane? (normal distributions are 2D and the final plot needs to be 3D). Any advice how can I do this? Many thanks!
