That's not detailed enough to be sure what you mean.

Here's my take on it: don't use a union to convert between types -- any
types.  That's not what it does.  Using a union in the way Rick has been
suggesting is simply a hack to get round the type system, and it works
for pointers because, on most systems, all pointers to the same object
use the same bit pattern.  I hope you will simply reject this hack out
of hand.  If you need to convert a value of one type to a value of
another type, C provides a way to do that with a cast (though for void *
you don't even need a cast if the context makes the desired pointer type
explicit).

As for your final design, I don't see any need to convert pointers at
all.  This all started because you happened to have a void * and you
simply put a cast in the wrong place.  But you don't either the void *
or the cast at all.  Maybe there will be, one day, be a need to convert
pointers, and I hope you will do that correctly with a cast, but in the
meantime I would imagine you can do most of what you want with a
discriminated union: place the common elements at the start of a struct
and include in those some type indicator.  After that, place a union
that describes the various different data that are specific to each of
your node types.

For your purposes, this whole discussion has been a distraction.
