What are the differences between the 20b intermediate housings and the

13B intermediate housing? Could the 13B >housings be modified or if you
were making an e-shaft from scratch, could it be made to accomodate the use
of 13B >intermediate housings to make a 3 rotor engine?

It is wider and there is a special main bearing.

There is a rumor that someone in Australia has done that. I would
copy the Mazda 20B exactly however and make a 20B style intermediate

housing.

I don't think there is enough room in there for a proper coupling and

main bearing

unless you copy the 20B intermediate housing.

Here is a picture of a three rotor shaft.

While you are at it you might as well make a four rotor engine.
Here is a drawing to copy.

This is in response to the 13BT derived 3-rotor.  This guy has custom
manufactured his own three rotor.

That was the guy in Australia I mentioned. I am a little skeptical about the shaft
coupling as we had some discussion on this engine quite some time ago.
I will look it up on the CD.
