[Cob] Cob/cordwood hybrid--plaster question...

[yew]

The husband and I are still hashing out our plans to build a tiny cob 
cottage on our 20 acres.  More and more I'm liking the idea of a hybrid 
building, mostly because of the speed of construction and the 
availability of free roundwood on our property.  Trouble is, the husband 
*hates* the way cordwood masonry (and "cobwood") looks.

So I'm wondering, is there any reason we couldn't just recess the logs 
slightly and plaster right over them?  We certainly had no trouble 
making cob/plaster stick to wood on our cob bench, so I don't imagine it 
would be much of an issue.  Am I missing anything?  Is there any reason 
why it might not work?
