Hi Stardust, unfortunately no I don't really see how it would be possible to do that with how Flow currently works. Surface to surface flow works by mapping from the UV structure of a base surface to a UV structure of a target surface. Multiple surfaces don't define a single UV structure anymore and so it wouldn't fit with how Flow works currently.

You might be able to get something like that done in a polygon modeling program, look into something like MeshMixer for example.

It's kind of difficult to apply polygon mesh style functions like that in MoI because the focus of MoI is on generating accurate geometry and things like discontinuities between surfaces don't really fit in well with that when they don't particularly bother a polygon mesh type program.
