Peter,
The 'Tree of Sonius' is basically not a vertical pole-style dial, but a
shadow plane dial. You are therefore free to arrange the hour lines any way
you like. So you might as well retain the tree shape. See the entry #11 in
my website on the Genk Sundial Park: www.fransmaes.nl/genk/ .
A colleague who is writing an article on moondials has asked if there is a website which gives the times of the moon's transit on a daily basis, and preferably from the user's location. Any offers?
Regards,
John Davis

The link to the site of Karl Schwarzinger didn't work but this one does.

Look for picture 40 (Bild 40)
The tree of Sonius is made of two separate plates and calculated as you
suggested.
A dial on the north plate and a dial on the south
