This has numerous problems:

* Its extremely slow for big meshes.

* Transforming the corresponding normals correctly is very difficult if
possible at all.

* It's very difficult to keep track of all the vertices this way.

* vtransform don't give access to the different parts of the transformation
(which I named X, Y, Z and P), and thus the correct weighted average cannot
easily be performed. If you insist that it can be done, please provide a
macro that takes a weighted average of any number of transforms.
