slight aero tweek: ground effect

[amankd]

a question came up in my ksp fb group for modding https://www.facebook.com/groups/1578621479074689/ about wheather ground effct could be in some way simulated, his query was regarding engins but i am more interested in the lift effects, how a wing within its wingspan in altitude will gain xtra lift and reduced drag, i have a pation for ground effect and wing in ground-effect craft, but would there be a way of setting this up, possibly by modding the lift drag ratio from the debug when close to the ground or maby having a seperate aero model like far within a certain altitude, it does not need to be perfect but i would like to know if somone can help, i have minimal cod ability but it would be somthing i would be able to learn, thakns for any help
