Hi, have those meshes and also uk mesh.
It wont replace your fsgenesis mesh, but will just write a new entry pointing to the new files for the terrain mesh.
Higher resolutions, just means sharper, more detailed terrain.
I find the Hawaii and California work well with Megascenery on top of the mesh.
You'll need to adjust your terrain resolution from 10 to 5, or vice versa to suit the new mesh.
