No way.  The GOTO_EXPRs and COND_EXPRs already exist.  Their memory
has already been allocated.  You are going to save *nothing* going
to the new form.  Indeed, you are going to allocate more memory for
the new nodes to replace the COND_EXPR and SWITCH_EXPRs.

Any argument for Zdenek's work will be independent of memory usage.
