Actually, that's substantially more complex since you're talking about an uneven kind of bending there where it would try to adapt to the changing shape of that blue object.

Currently your best bet for these kinds of deformations is to use Rhino v4 to do them: http://www.rhino3d.com/ - you can import your MoI Model into Rhino and then use Rhino's FlowAlongSrf command to apply the deformation to your object. Then you can export your model out of Rhino and back into MoI.
