  Firstly: You can't modify an arbitrary object with an isosurface.

  Secondly: Yes, you can modify an isosurface function with another function.
But is this really a transformation? When you modify a function with another
function, you just create a third function. There are no specific
transformations involved.
  Yes, you can, for example, convert a cylinder-shaped isosurface into a
cone-shaped isosurface. This is, however, done by actually creating another
function, not by transforming.
  Of course it is possible to think that any transformations are possible
for an isosurface if you like.
