I think that the problem using that aproach is that parent items are UL, then you try to hide them... and the browser hides all the LI too?
You’re totally right - sorry for that wrong idea.
Here’s a better one, I tried it successfully:
Use the Parameter &parentRowTpl refering to a chunk which contains the following code:
<li [+wf.classes+]>[+wf.wrapper+]</li>
So it contains only the [+wf.wrapper+] for the children, but no [+wf.link+], [+wf.linktext+] a.s.o. (what you have in the default &rowTpl).
Let’s say, you name the chunk ’blind_parent’, then your Wayfinder call should read like this:
[!Wayfinder? &startId=`###` &level=`2` &parentRowTpl=`blind_parent` !]
where you have to replace the ### by the appropiate Id (the parent of the A, B, C...).
Good luck!

Edit: I corrected a typo - it has to be &level=`2`.
