Can wax be rotomolded for sculpture?

In the lost wax process for bronze sculpture casting can a wax pattern be rotomolded ? Has anyone tried this before?

If you look at microcrystaline waxes or generally for waxes used for making jewelry, there are a considerable variety including ones for machining, carving, casting, and hand molding. Some machinery sites (MSCdirect.com I think) have blocks of wax for training people to machine metal without the expense or risk of damage to machine or operator from starting on metal.
Reviewing this article http://en.wikipedia.org/wiki/Rotational_molding shows that wax and chocolate were first uses of rotomolding and chocolate continues. There is not reason it couldn’t be used for lost wax.
I have made wax shells in the same plaster molds I used for slip casting clay – pouring in wax, rotating the mold by hand and pouring the excess out – getting a very uniform layer. see here http://users.ticnet.com/mikefirth/castgobl.htm#LGGOBPROJ and up and down that page. Any method that makes wax pieces to be added to sculpture lost wax seems perfectly legitimate to me – see 3 molded hands welded to make goblet stem, etc.
