Deforming Pattern out of Regions bounded by a Region

I am working on a definition to deform the ceiling pattern of the Farnese palace so that it moves out of the boundaries of the buildings in plan but stays within the greater rectangle. I also want it so curves do not overlap. I have tried to make a definition in grasshopper, using a small section of the pattern but it is not doing what I want it to. I am new to this and any help would be greatly appreciated.

The picture I uploaded shows the yellow force moving curves outside of the buildings in plan, while the other arrows demonstrate the force to keep moved curves within the large rectangle. 

My definition deals with 3 sets of curves (the outer rectangle, the curves to deform [pattern has ovals], and the buildings [rectangles] in plan).

PLEASE HELP ME :)
