In case you are still looking: FunnyLori posted a picture of Wilhelm on a Batchix Lagoon body: Click to Tumblr.
I know this is quite the old thread, but just stopping by to say I have a Wilhelm head in white and I'm on the search for a suitable body for him (casually). I'm working on finding each of my floating heads a body this year and next year (along with commissioning art for everyone as an on-going endeavor), so I'm very curious as to what people have tried! It's quite the challenge to find a neck in the 5-6cm range, it seems!
I have tried a Granado 32Adagio body. The proportions are nice, but the neck is much smaller than the Chicline body the Wilhelm head was designed for, so there's a gap between the neck and the neck hole in the head.
